"The Sonoma Dream Team (YES! They are that good!) Buying a home in Sonoma while living on the East Coast couldāve easily turned into a logistical headache, but Cassie & Matt made the whole thing feel surprisingly manageableāand honestly, enjoyable. With only a short window to see homes, they built a schedule that made every minute count. They guided us through the offer process, inspections, and all the followāup pieces with a level of organization, clarity, and steadiness that kept us grounded from thousands of miles away. What we appreciated most was how proactive and prepared they always were. Anytime we thought, āThis part might get complicated,ā they were already ahead of it. No drama, no scramblingājust smart, thoughtful guidance. Theyāre an impressive team: professional without being stiff, friendly without being salesy, and genuinely invested in helping us land the right home. By the time we closed, it felt like weād worked with people we trustānot just REALTORSĀ® who got the job done. Weāve worked with agents around the country, and this pair stands out. If youāre buying in Sonoma, youāll be grateful to have them in your corner." -JB

"Cassie is a dream. We recently worked with her to purchase our home (our third time purchasing) and Cassie made the process easier than I could have imaged. From taking us to see the home, making an offer days later and expediting our closing - she was able to get us into our new house in a matter of weeks.

"Working with Cassie was an absolute pleasure from start to finish. As first-time home buyers, we had a lot of questions and uncertainties, and she was incredibly patient, knowledgeable, and reassuring every step of the way. She took the time to truly understand what we wanted and was strategic in helping us navigate the market, offering honest advice and smart guidance that made us feel confident in every decision. She was also extremely flexible with showings, always accommodating our schedules, and made the entire process fun and engaging rather than stressful. She consistently went above and beyond, advocating for us, communicating clearly and promptly, and making sure no detail was overlooked. If you're looking for someone who is professional, personable, strategic, and genuinely invested in her clients, we highly recommend Cassie." -GP

"I highly recommend Cassie Bost. I was flying in from out of town to look at houses and she was extremely organized in showing me a wide variety of properties in Sonoma and Napa in a short period of time. She was extremely knowledgeable, responsive, ethical, and calm. She guided me through every step of the process of buying a home and helped me make decisions that worked for my situation. She also went above and beyond and helped arrange for a short term rental as I waited for my house to close and connected me to folks who could help make some updates and repairs. I canāt say enough about the positive experience I had; it is so nice to feel you can trust and genuinely like the REALTORĀ® you are working with on such an important purchase." -LH

"Cassie is genuine, and willing to go the extra mile as a REALTORĀ®! We were able to close our home early, and get a deal for a home that was valued higher than we paid. A challenging and competitive market in 2025, yet that did not stop Cassie from helping us get the house we wanted within a few months. She knows when to step in to give guidance, and step back when to let you or your partner brainstorm. So if you want someone who really cares, and will help you persevere when the going gets tough, then call Cassie" -James W.

"If there were 10 stars, I would choose it! From the moment I met Cassie, 8 months ago, I felt at ease talking with her. As time passed and we toured numerous homes together, my confidence increased and I knew she would be the one to take us through the home purchase process. Now, here we are crossing the finish line, and while I am happy about the home we are buying, I will be miss our frequent communications, her good advice and steady personality. Cassie also has a refined eye for choosing colors and visioning the interior design possibilities. I recommend her as a real estate agent without reservation." -Dawna L.

"Would give Cassie more than 5 stars. She was very diligent about details, sharing information and keeping everyone informed along the way. Anyone will be fortunate to work with her on their real estate journey." -Judi
