Client Testimonials

Colleen, Rebecca and their team are the reason I was able to buy the house of my dreams. No question. In addition to helping me sell my current home (easiest thing ever, honestly, because of them), Colleen and Rebecca found me the perfect home, got me in early for a viewing, worked with my challenging travel schedule, helped me write a pre-emptive offer, negotiated, coached, found me the best banking and closing and appraisal partners, and closed my house in unbelievable fashion. Each one of these steps had many possible times when we could have failed, but this team was fantastic. I could not have been happier, and this was even an enjoyable experience if you can believe it. I miss our regular chats and meetups now!

Colleen, Gretchen, and Rebecca assisted us in buying our first home. They were excellent in every respect and below are just a sampling of their strengths in this field: - they were very knowledgeable about San Francisco and the market - they were very quick in their responses and were able to adjust quickly to new developments in our negotiations and sale process - they are very well connected and well respected amongst realtors. Sellers’s agents would light up when we mentioned we were working with Colleen We felt very confident working with them that we would get the house we wanted (even in this competitive market) and we did get it!

As first time sellers in San Francisco, we needed someone who understood the inner-workings of the market and sales season. We chose Colleen and her team for good reason. They are reliable, experienced, well-connected, and thoughtful.

Colleen and Rebecca worked with us to get our home tastefully ready for market, paying attention to our budget, our schedule, and our personal needs. For example, they helped us secure a beautiful staging service for a price in our comfort zone. With our four children taken into consideration, they showed excellent interpersonal skills - making sure the experience would be positive for all parties involved.

They wisely coached us through the offering process. Our final result was top dollar with no contingencies - a credit to the important preparation they had put into our home before listing it.

Throughout the process, I trusted them to represent our family and our home cleanly, confidently, and professionally. As first-time sellers in San Francisco, we needed someone who understood the inner-workings of the market and sales season. We chose Colleen and Rebecca for good reason. They are reliable, experienced, well-connected, and thoughtful.

My husband and I hired Colleen to help us with the sales of our newly built 9-unit luxury condo building in the Mission District in San Francisco. Working with Colleen truly exceeded our expectations. Her expertise was essential to the success of the project. She is knowledgeable, approachable, and very generous with her time. She was always well prepared and enthusiastic. She proposed an efficient sales process, helped us arrange for the staging and photographs, and in the end, all nine units sold very quickly and was a huge success. I can’t say enough great things about working with Colleen and will always seek her advice on all things related to real estate.
