Sarah & Lotte came highly recommended to us by two friends who had their homes sold soon after they were listed thanks to Sarah & Lotte’s extensive knowledge of the West Marin housing market. We worked with Sarah and Mia who were 100% responsive and professional. Sarah’s intuition and guidance on positioning our property was perfect. We were impressed with the success of the marketing, showing, and sale of our home, starting with the beautiful marketing materials and ending with the smooth sale transaction. These were challenging times due to the Covid-19 pandemic but Sarah was adaptable and guided us through the new requirements.

– John and Cynthia Harland

Lotte Moore is a lovely woman to work with. She is attentive and patient, responsive (almost immediately) to phone calls, emails and texts. She brings an enormous knowledge of the real estate market, and the real estate market specifically in Marin. We sold our condo, after we moved out-of-state, (and during the Corona virus) leaving Lotte and her staff to clean, stage, prepare and show the property. Can’t say enough nice things about Lotte and her staff.

– Diane Gusick

From the beginning Sarah has been great to work with. Personable, a good listener, with clear ideas about how to go forward. Recently Sarah helped us buy a new home in West Marin. She sprung into action, joined us at the site on a major holiday, got an offer in that night, gave us contacts to get a septic inspection right away, and guided the process through in just a few days. Her experience, negotiation skills, practicality and charm was our good fortune, and we would recommend her highly. Thank you Sarah and McGuire Real Estate.

– Rachel C Gaunt and Frank Leahy

I asked Lotte to represent us on the sale of our home because she sold my next door neighbor's home for over $3 million in 8 days! It took her a little longer to sell our home because the Corona Virus slowed down her excellent team , as they arranged for an estate sale to sell what we did not want to move, and to give the rest to Good Will. It also took her crew longer to spiff up our home and get it staged for the same reason. The home never went on the market. She advised her colleagues of the the temporary availability of the home prior to it being listed. There were six bidders on the home in the next week. Two were above asking price and one had no contingencies! So, things could not have gone smoother or better in our opinion. We strongly recommend McGuire Realty in general and Lotte and Sarah in particular.

– Tony Eason, M.D.

My wife and I were very pleased with Lotte and Sarah. They were accommodating, friendly, thorough, and professional in their approach to selling our house. They listened to our issues and suggestions. I would definitely recommend them to either sellers or buyers.

– Steven Brown

We couldn't have been more pleased with our experience with Sarah, and team Lotte and Sarah. Their professionalism, responsiveness and extensive knowledge of the Marin real estate market were amazing. Their team had high-quality marketing materials put together in a heartbeat, they built a thorough and elegant website for our property, and Sarah and her support team was with us every step of the way. We went from discussing our listing, to closing our transaction in ~3 weeks. We were very pleased with the outcome in every sense! We can recommend them without reservation.

– Julie Rocherolle

Sarah and Stephanie, of Team Lotte, were outstanding in finding a house for us. They had been recommended by a friend. They showed us around numerous properties before we found a perfect fit. When the seller wanted a quick close they calmly made it happen, despite unexpected hurdles. Even after closing Sarah was happy to offer advice and stay in contact. They were prompt in returning calls and swift in resolving questions. I would strongly recommend their services!

– Mel and Chris Bebbington

Lotte and Sarah offer a broad set of skills: knowledge of the Muir Beach and West Marin real estate market, negotiation skills, attention to detail, warm and friendly personalities and patience. They were always accessible and listened carefully to our many questions. We were especially pleased with the video and brochures describing our property. As evidence that we made a great choice in retaining them, we had an offer within days. And despite issues raised by the coronavirus disruptions, we closed on time. Lotte and Sarah are true professionals in every respect. Tom Friebel

– Thomas E. Friebel

Sarah and Mia of McGuire Realty, listed and sold the family home for my brother and I. Both Sarah and Mia were available to direct us to do what was necessary to make the home the most sale able in the time frame we had to work with; this was no easy task since this home has been with our family for over fifty years and was not only full of memories close to our hearts, but also full of family items close to our hearts and much care needed to filter through four generations of things only my brother and I could value and assess. Much understanding was shown by these realtors and when it came to professionalism with other realtors when offers started coming in, our realtors always had our best interests in mind. I would not hesitate to recommend this realty outfit to others looking for help selling or buying a home.

– Rick Raddue

Lotte and her entire team were exceptional! We had a duplex to sell and timeline to meet with our 1031 reverse exchange and Lotte came up with some creative ideas to make it happen with 15 days to spare! We were very fortunate that it was all cash with no contingencies and a 10day close on March 4th....just ahead of this pandemic! We were impressed and very fortunate! All of Lotte's team are attentive, responsive and professional... even delivered/picked up documents as necessary... We would highly recommend her.... she's diligent, knowledgeable and most of all enjoyable to work with... Lee and Margo Kirkpatrick

– Lee and Margo Kirkpatrick

Lotte and her team provided outstanding customer service and showed a real commitment to providing us with the best results possible. I would gladly work with this team again in the future.

– Peter Chow

Great Job on the Kentfield home. Very Professional. Thank You.

– Carl Schneider

We just sold our Belvedere home with Lotte & Sarah in a record time of a week! Lotte had sold us the same house just 3 years earlier, and that had been such a positive experience that we knew we’d work with her again. Sarah and Lotte, together with their office support Stephanie, are a slick team - efficient, proactive, highly competent and professional- in a league of their own! They act with the highest integrity and transparency and it was a pleasure to work with them. Most of all, they are really nice people. Thank you ladies!

– Carol Bagattini

We had just moved to Marin from Vancouver, Canada, and were given Sarah Kowalczyk's contact. She and her team went out of their way to get us informed on the US real estate market and helped us find the perfect house for our family. We could not be more happy. Thanks!

– Ginene Hutchison

Lotte and Sarah, the dynamic duo of Marshall! We have purchased a lot of homes in the past and yet we were so impressed with Lotte and Sarah's customer service and attention to detail. They not only get the job done, they always do it with kindness, big smiles and warm hearts.

– Sophia Lin

Sarah and her team were fantastic! When presented with our tight moving timeline, Sarah and her team rose to the occasion and provided us with some amazing customer service. Everything was very well organized, and presented to us in a palatable manner which helped us make difficult decisions quickly and efficiently. Further, because we were out of country buyers, we leveraged Sarah's in-depth knowledge of the area, it's school systems, recreational activities etc. to help us navigate the local Marin market. Sarah and her team were the perfect fit for us, and provided us with everything we could have asked for in an agent. Brian and Ginene

– Brian Hutchison

We knew right away when we interviewed Sarah Kowalczyk that she was the sort of real estate agent we were looking for. She was polite, intelligent, and, most important, thoroughly prepared and knowledgeable. She had, in short, all the professional qualities and credentials we needed. Her capability was proven almost immediately. Clients she brought with her on the very first day to view our house bought it shortly thereafter. The entire procedure could not have been more smooth or well handled. It is necessary also to mention that Sarah's assistant, Stephanie Kirkwood, proved equally capable and helpful in every respect.

– Francis John Seidner

Lotte and Sarah did an outstanding detailed --no hassle for me- job of selling my house. Would 100% recommend them in all cases. Chuck Laurenson

– Charles P Laurenson

Lotte and Mia were incredibly patient and helpful throughout our home search and purchasing process. During the home search they kindly provided helpful information about neighborhoods, specific home considerations any other noteworthy information relating to the home. Lotte patiently walked us through how the home purchasing process worked from beginning to end, thoroughly answering all of our novice first time homeowner questions. Lotte and Mia went above and beyond in showing us homes and guiding us through the overall process. We cannot thank them enough!

– Mariel McCarter

Lotte and Sarah are very experienced, efficient, thoughtful, thorough, and you feel their professionalism at all time. They sold our house in Mill Valley in 24 hours and at no time did we feel lost or uncertain of the process. We loved working with them, and the rest of the team and recommend them with absolute confidence.

– Chloé Lagier

I can't say enough good things about Lotte and Sarah. They are exceptional. Smart, personable, hard-working, experienced...everything that you want in a realtor, and more. With my transaction, which was mostly handled by Lotte, I always felt that she was genuinely concerned about me and my experience, and went the extra mile to be helpful and available. I feel so fortunate to be working with them on my next transaction.

– Jann Moorhead

Lotte and Sarah helped me with a purchase in West Marine. It was quick and efficient transaction. Thank you!

– Michael Schwarz

We recently sold our house of over 50 years in San Francisco with McGuire. We were recommended to ‘team Lotte and Sarah' by a friend and from the onset they took a real interest in understanding our family, the meaning and value of our home to us, it’s unique characteristics, and even researched to discover the famous architect who built it. My primary contacts were Sarah, Michaela and Mia. Everyone was very personable, competent and hardworking, bringing a lot of passion to their respective roles. Documents were streamlined virtually making signing easy. The team was responsive by email and text and addressed issues that arose. They referred excellent tradesmen and diligently coordinated the work to prepare the house for sale. Sarah fine-tuned the market listing and ultimately the house was sold with the best of scenarios. They also generously shared their resources and recommendations, expertise and insight throughout the process, and worked with me through many questions and decisions. Then to wrap up our collaboration, we received a beautiful bouquet of flowers to celebrate a successful conclusion - a wonderful touch. I can highly recommend the women of ‘team Lotte and Sarah’.

– Allison

Lotte and Sarah were absolutely full service from long before we opened escrow to long after closing! They were always incredibly responsive and we felt like they had our backs on every detail. Ours was a wonderful experience!

– Tina Marie Humphrey

Seamless experience Great team. Thank you!

– Diane R.

My McGuire team was terrific - smart, quick, considerate, always available, and a delight to collaborate with. When we hit a glitch they were creative and on the ball with an alternative. My buyers are a dream and the process was as smooth as could be. The best.

– Karen Gray

Fantastic experience. Wonderful, thoughtful, kind and enormously professional and knowledgeable. Would hire them in a minute. We worked with Michela mostly and her knowledge, assistance and personal attendance to both of us was top notch. Really liked everyone I met on this team. Superior people!

– Trudie and Bruce scott

I have been working with Sarah and Lotte on real-estate deals for over 20 years, and they have been our go-to partners in the SF Bay area. They are hard working in the old sense of RE brokers - they earn their commissions and they work hard for their clients. I will gladly continue working with them.

– Gal Bar-or

If you like working with experienced, thoughtful, thorough, efficient, get-it-done people, Lotte and Sarah’s team is the one for you. I loved working with them all and recommend them with absolute confidence.

– Staci Hartman

My husband and I have known and worked with Lotte for over 10 years. Our first purchase was in Larkspur back in 2010, and in 2017, she helped us sell it. We were able to list and sell the home within 5 days! She made the selling process so easy for us, and removed all barriers. Her recommendations were spot on, and the marketing for our property was perfect! Over the past 18 months, she has been tireless in her pursuit for our perfect home. She never pushed us into anything just to make the sale. Lotte is definitely focused on meeting your needs, and has a true gift in getting the deal done!

– Bernice Brown

Lotte and Sarah make an exceptional team. They are dedicated, intuitive, and hard working agents with a special skill at bringing dreams to life.

– Lynn Lockie Camastral

This team provided expedited and accurate guidance to correctly price and stage our home for sale. They carefully and patiently took us through their strategy, culminating in multiple offers and the final selection which allowed for a straightforward close benefiting both us and the buyer. Their professionalism is a dynamic and compelling blend of real estate and negotiation acumen along with the necessary empathy required for most people who are parting from or acquiring their most valuable, personal and prized asset - their home. Whether listing a property or searching for your next home, I highly recommend Sarah and Lotte.

– David Cook

Lotte and Michela were SO great to work with. Super professional, knowledgeable and fun! My wife and I highly recommend them!

– Jeremy Devich

My husband and I were doing a 1031 exchange with a house we owned in Colorado, so it was critical to be able to find a great property here in Marin County within 45 days of closing on our Colorado house. In the current tight housing market, that was going to be difficult. Lotte was "on it." She identified areas for us to begin looking, while our Colorado home was on the market. When we did find a great condo in Greenbrae, she helped us close the sale quickly and smoothly. Thank you Lotte!

– Carolyn Kohler

Lotte & Sarah - thank you for working diligently and consistently to get a great result with the sale of my property. Very happy!

– Tim Lyons

Lotte and her amazing team helped our whole family with a multple purchases in a newly constructed Condominium project, which had it's own set of unique twists and turns, but their constant support and seasoned experience made the multiple transactions happen simultaneously . We are so grateful for their work they did for us.

– Suzanne Leonoudakis

Sarah and Team were highly efficient. We were in contract within a week upon putting our home on the market. I would highly recommend them to anyone who wants to sell their home fast and for a fair market value.

– Jane Teel

Sarah was recommended to us by a colleague at work and boy did she deliver. We haven't bought in 10 years and so much has changed since then--especially the Bay Area market! Sarah helped us navigate the challenge of buying in Marin and helped us find a real gem (below market value!). What you can expect from Sarah and her team: responsiveness, insight, and humor. The website is user-friendly and sent us great recommendations as soon as they were listed. When we identified a place we were interested in, Sarah or her associate Michela met us there promptly and were flexible with our work schedules. They let us come to our on conclusions but answered every question we had. Two thumbs up!

– Jared Baird

Sarah and her team were terrific and I strongly recommend them! they were super prepared for the whole process of selling. They brought outstanding marketing materials to the job. When problems arose, they were great at "calming the waters" and providing good solutions. And, they were understanding of our personal schedules and accommodating to them. All in all, they led us through the smoothest, most successful real estate transaction we've ever had. Thanks Sarah, Lotte and Michela.

– Tony Torrance

We so enjoyed our experienced with Sarah and Michela. They were available for all of our questions, giving us their professional take on each step. They were also very patient, answering all of our first-timer questions. They gave us the benefit of their expertise while allowing us to make the final decisions, without any pressure. Our process could not have gone better, and we very thankful for all of their help!

– Josh Frechette

The McGuire team we chose to sell our Mill Valley home was stellar. The home sold in less than a week for 30% over asking; great success by all measures. And due to their strong expertise, careful guidance and professional, warm manner, it was a wonderful experience as well. Thank you Lotte/McGuire!!

– Linda Raker

I am grateful for Lotte Moore's integrity and loyalty as a colleague. She is extraordinarily skilled in the mechanics of her profession and unusually sensitive to the emotional aspects of personal transitions in life.

– Christopher Raker

Michela is, simply put, the best. She worked with me, patiently, as I am now a first time homeowner and didn’t know how the process worked when we got started. She is creative and knowledgeable and always had my best interests at heart. She talked me out of a few places that were totally wrong for me and she helped me find the perfect place to call home. The Lotte, Sarah, and Michela team is amazing and I can not recommend them highly enough.

– Rachel Zarrow

I am in the real estate business but chose to work with this unbelievable TEAM of Lotte,Sarah and Michela!We wanted a quick close and with their Teamwork and strong marketing we received 8 offers and closed in 7 days! Ted and Helen Abe Realtor/Homeowner

– Ted M. Abe

Sarah and Lotte are an amazing team to work with. They will exceed all of your expectations. They have attention to detail down to a science and they will communicate with you every step of the way. The journey with them begins with asking great questions, listening well and then helping you get what you want! If you are looking for first class service all the way through then this is the team to go to !!!

– Helen abe

Sarah and Michela were wonderful to work with! They were professional, patient, kind and creative and we’re thrilled to be in our new home! I’d highly recommend them to anyone buying or selling.

– Allison Tryk

Lotte & Co. did an excellent job in getting us oriented to Marin County and the housing / living opportunities and neighborhoods. Lotte was very patient with our questions and concerns and was able to help us find a fantastic home for our family in Mill Valley. We could not be more happy & satisfied with her professional time and attention she put into finding us a home!

– Kieran & Jackie Phelan

Lotte, Sarah, & McGuire staff did an excellent job orienting us to the Bay Area & housing market. They were very responsive to our questions and concerns and worked hard to understand our preferences and budget and facilitate our relocation to the home of our dreams. They went above & beyond our expectations and found the perfect home to start our new life & adventure in southern Marin County!

– Kj Phelan

Sarah and Lotte could not have done more for us! Sarah had to sell our house, a 100 acre farm, and if possible the farming business. Sarah is very smart, diligent, and fun to work with . She accomplished every goal, and found us our next perfect house! She really is the very best, putting lots of time into the project and representing her client's interest every step of the way. We had tried for several years to accomplish a sale, without any results until Sarah came along. Because of the nature of the property it didn't happen overnight, but Sarah pulled it off in spades. You will love having her on your side!! Five plus stars!! Thank you Sarah and Lotte!

– Warren Weber

My husband & I worked with Sarah & Lotte on both selling & buying. The property we sold was not your typical listing. It was a multi parcel large rural property which took several hours to show properly. Sarah was on it from day one! She gave each showing the time it required and brought creative ideas for each potential buyer. She is super smart, hard-working & knows her business. She brought integrity, a great attitude , & a smile to every interaction. We have the utmost respect for this team & would definitely work with them again.

– Amy Weber

My husband and I are in our new home, all thanks to Sarah and Lotte and their team, including Michela! They were so great about getting us into see houses we were interested in, and their sincere care was so evident in every interaction. Once we found a home, it was a challenging process, as we had to have an FHA loan. They were so helpful, and are so grateful. In an industry that can be face paced and impersonal, this team is personal, compassionate and extremely effective. They are also fantastic negotiators, with tremendous creativity and great instincts. I can't recommend them more highly. Meegan Lee Ochs-Potter

– Meegan Lee Ochs-Potter

Kim and I had the pleasure of working with Sarah and Lotte on four home transactions -- the purchase and sale of our homes in Sausalito and Tiburon. In each instance, the buy was at the right price and the sales were top of the market. The combination of market knowledge, use of data and deal savvy made for a terrific customer experience. Sarah listens, informs and takes action; she is the best.

– Edward Lange

We were so pleased with the strong negotiations that Sarah did for us when we sold our home in Corte Madera. She has a soft and sweet exterior, but is extremely strong and intelligent. She knows when to be silent and when to speak which is very important! We consider both Sarah and Lotte to be great resources for any real estate dealings that we have.

– Kay Keohane

Lotte is professional, thorough, and caring! She helped me find my dream home. I had worked with others for two years. When I switched gears and asked for Lotte's help, she listened to my needs, hopes, and desires. With great patience and spunk, she showed me many homes to give me a clear idea of the market and my options. Then, she found me my perfect spot! And, again with knowledge of the process, resources, and encouragement, I bought it! Thank you for helping me with Home Sweet Home, Lotte!~

– Kathy Geissler Best

From the first time we met with Lotte, we knew we were working with the best. Lotte is not only an expert in real estate, but she has such a lovely way with people - friendly, elegant and kind. It was so much fun to tour houses with her. She was always warmly welcomed and obviously has great relationships with everyone in the business. She loves what she does and it makes the process of touring and making offers such an enjoyable experience. I was amazed by her boundless positive energy. In addition, she has incredible knowledge of neighborhoods, the market, and what to look for when considering a house to buy. We ended up buying our dream home in an area we wouldnt have thought to consider if it hadn't been for Lotte's urging that we go and spend an afternoon exploring there. And when we were ready to put an offer together, it couldn't have been at a less convenient time for all involved. But both Lotte and Sarah were on it without skipping a beat. The deal involved some creative problem solving and Lotte kept working on getting us the best possible outcome until the very end, beyond what we would have asked for. We trusted her guidance and despite buying at what seemed the very top of the market, our home has increased in value considerably over the few years we've lived here. I cannot recommend Lotte and Sarah enough. They are truly the very best.

– Nicole Trautsch

We all want to do business with those individuals and companies who are responsive, transparent, honest and knowledgeable. My dealings with Lotte and Sarah, have hit each one of these benchmarks. Would recommend this team to any home buyer. Toby Mumford

– H.G. (Toby) Mumford

Sarah and Lotte sold my house in Ross. It was a home of 24 years and a rather complicated time. They not only took over the sale of my house but also comforting me. Rather than a stressful, difficult move, it turned into a breeze and established new friendships. They are professional, kind, and fun. Five stars. No, ten.

– Jeanne Barr

Based on a recommendation from a good friend, we contacted Lotte after purchasing a condo we planned to remodel and sell. As soon as we met her, we knew she was someone we wanted to work with. She came to the meeting ultra-prepared, was super professional and personable. It was obvious she really knew what she was doing and we found it easy to trust her from the very beginning. Throughout the entire process of remodelling, staging, photographing, listing and selling, Lotte gave us great advice, assisted with a sticky situation we encountered with a tenant in the building, listened to what we were hoping to achieve from the sale, ensured the whole process went as smoothly as possible and pushed hard to help us achieve our goal. Whenever anyone talks about buying or selling in Marin, we always refer them to Lotte and her partner Sarah.

– Andrea Griffin

Sarah and Lotte are simply the best realtor team in Marin. Period. Sarah helped me sell my home in Woodacre (which took a while because of the recession; yet Sarah was always patient, understanding and looking after my best interests) and purchase a lovely new home in Sonoma County. Sarah is truly brilliant, highly experienced, very responsive and extremely savvy when it comes to negotiating. I couldn't be happier with the manner in which this team operates - again, simply the best!

– Mary ONeill

Lotte and Sarah provided us with an honest, thoughtful, and effective counseling and negotiating team for the purchase of a our 2nd home in Point Reyes Station. We would enthusiastically recommend them both to other buyers and sellers.

– Don Morrill

When we purchased our home here in Marin, the transaction was complicated by us residing overseas and having a compressed time in which to find a home. We were dealing with all sorts of transitioning decisions and were fortunate to have Lotte in our corner. What an amazing agent! She was well-prepared, extremely knowledgeable about the market and the inventory, went to a great deal of effort to understand our needs, helped us to explore and reflect on our options, and made our purchase decision painless. Lotte was patient, encouraging, extremely helpful and supportive, and we consider her to be the best agent we have ever worked with. We also spent a day with Sarah and it was clear, they are a great team, who rely on one another and work as a partnership.

– Carol Bagattini

Lotte and Sarah were w dream to work with. They really listened to our needs and were very patient through the process. They learned who we were and were able to bring us a very unique home. Couldn't be happier and have already referred them to several friends.

– Robert Balmaseda

I had the great pleasure of working with Sarah twice, as a buyer and a seller. Sarah is the ultimate professional. She takes care of everything and no detail however small is missed. This woman knows her stuff!

– Lucienne Hoffman

Lotte and Sarah are the most professional, knowledgeable and responsive real estate team I have ever worked with. I have purchased many high-end single family homes in Marin County and have worked with many different realtors over the years. Lotte and Sarah are simply the best, and are totally dedicated to providing an "added value" and meeting the clients real estate objectives.

– Robert Thull

Lotte and Sarah,In both my real estate dealings with them, proved to be reliable, well-informed, professional, ethical and knowledable . Their pleasant personalities along with their helpful guidance through all the transactions were great assets. I would hightly recommend these realators to anyone interested in selling or buying property. I have been completely satisfied in every respect of my transactions with them and the company.

– Barbara Tarasoff

Sarah and Lotte are so gifted at what they do. They are smart powerful and kind and the kind of people who you'd invite over to dinner in your new beautiful dream home they made happen!

– Elizabeth Gorek

Lotte and Sarah did a great job representing us as buyers of our first home. They provided very good advice and exceptional service. Also, tenacious negotiators. Highly recommend them both.

– Paul glover

We only have the very highest praise for Lotte who found us our dream house a few years ago. She was completely professional in every regard and a total delight to work with.

– anonymous

I had the pleasure of working with Lotte on several transactions. She was always professional, negotiating expertly with both sides to create a mutually beneficial agreement. Sarah was exceptional in supporting her partner during the process.

– Annette B

Lotte and Sarah made all the difference! They gave expert, detailed recommendations on how to improve our property in preparation for sale in order to achieve the highest return on our investment. They also guided the sale so that market timing and pricing hit the perfect sweet spot, resulting in a full-price sales contract just 5 days after the house was listed! Uber-professional and forward thinking, I would return to this dynamic duo in a nano-second for my next real estate transaction.

– Norm Hunter

Sarah helped my buy a house for my son in Petaluma. Her work was absolutely stellar! She negotiated a good price, worked diligently with the other agent to make the sale happen, stood by me through the entire process, made buying recommendations that saved me thousands of dollars. I've bought many houses over the last 40 years, and my work with Sarah was the most outstanding and satisfying of all transactions. I highly and unequivocally recommend Sarah to you for your next buying/selling project.

– Frank Werblin

My husband and I sold 2 homes and purchased one through Sarah and Lotte! We also used McGuire when we sold our San Francisco Condo for above asking! Our experience with Sarah and Lotte as well as the rest of the McGuire Team has been first rate all the way around! We highly recommend Sarah and Lotte for all your Real Estate needs!

– Kimberly Lange

My wife Beth and I worked with Sarah to find a place in West Marin. She is very knowledgable and helpful. Sarah located a place for us and guided us through a complicated transaction because the seller was a family trust. Sarah was a tough negotiator. She kept us well informed. She gave us good advice. We are the proud owners of the home we sought.

– Barry Gorelick

I highly recommend Sarah Kowalzyck as a real estate broker. I was incredibly impressed with Sarah's dedication and support throughout the process of selling my Marin home and purchasing a home in San Francisco. Sarah was professional, resourceful and completely present and accessible throughout my entire home selling and buying process. I know Sarah had many other active listings while she was helping me, but she made me feel like I was her top priority. She is savvy and incredibly smart. If I were to sell or purchase another property, I would hire Sarah again without hesitation.

– Susanne C

I have never seen two more competent, hardworking, professional REALTORS. I have been blown away by their service. I highly recommend them.

– Jennifer A.

Whatever potential your house has will be realized in their capable hands. They are charismatic, imaginative and confident. Their attention to detail is meticulous and their presentation of your home will be stellar.
