About Steve

Steven Mavromihalis has been assisting clients with their residential and investment property needs since 1984. Steven has founded and manages several San Francisco-based enterprises that invest in real estate and real estate related products and services. With business partner Gil Fleitas, he has most recently co-founded THEO, an online platform that seeks to support real estate professionals in providing superior service to their clients.

In his brokerage practice Steven is supported by a highly specialized team that have helped him build one of the industry's most successful commercial and residential practices. Working in true partnership, the Byzantium team provides each client with highly individualized service.

Steven has consistently set record sale prices for both residential income and luxury homes over the span of nearly three decades. Since 2001, Steven and Byzantium has been ranked by The Wall Street Journal as one of the top-producing teams in the U.S.

In 1992, Steven became a founding board member of the Homeless Prenatal Program (HPP) in San Francisco. The program provides prenatal care to homeless women and supports their efforts to conquer substance abuse and find housing and stable employment. Since then, the HPP has helped tens of thousands of women and their families and has become one of the most awarded and highly recognized nonprofit service providers in the Bay Area. Steven is past president and remained an active member of the program's board of directors for more than 15 years.

Client Testimonials

★★★★★ "I could not recommend Steve highly enough. He is smart, knowledgeable and is always ahead of the curve. He leads you through the process (selling in my case) and keeps you informed of each step along the way. You can depend on his advice because it comes from years of experience. Above all, he is totally honest. I would recommend him to anyone who either wants to buy or sell high-end real estate. " - Robert W. Felton

★★★★★ "I have worked with Steve for nineteen years, on over a dozen transactions. Steve is a very savvy negotiator, has comprehensive knowledge of the San Francisco market, and demonstrates a relentless drive to succeed on behalf of his clients. He also has a fabulous team working for him, who are instrumental to his success. Every single one of my sales was record-setting thanks to his astute advice on how to best prepare and market my property, and due to his and his team’s hard work on my behalf. I would not dream of ever buying or selling without him in charge of the deal." - N.R. Investor/Owner

★★★★★ "In advance of choosing a real estate agent to assist me in choosing a home in San Francisco, I extensively interviewed several such agents and happily chose Steven M. and his team to work with me. The process of finding and selecting such a home was seriously challenged by virtue of my going through the dissolution of a long term marriage coupled by the complexities attendant to dealing with a co-op property whose legal documents were sorely out of date. Steven exhibited great patience as he shepherded me through the process of identifying the “right” home for me and his team literally worked into the early morning hours for several days dealing with the arcane complexities of co-op rules and regulations necessary to satisfy my lender as well as myself. My endorsement for him is unequivocal to anybody considering engaging his services including myself when and if I wished to undertake another residential real estate transaction." - Sy Kaufman, Founder of Crosslink Capital

★★★★★ "My family used Steven to purchase our first home over 10 years ago, and when it came time to move, we had no hesitation in calling him to find our new home - we would certainly recommend him to our friends and family. Steven is incredibly honest and patient; it is obvious that he cares more about finding the 'right' home for his clients than just making a sale. Steven's upbeat personality and sense of humor make working with him a pleasure, and his extensive knowledge of the market helps ensure you are making the right decision. Steven is very easy to reach, and if he is unavailable, he has a very competent and responsive team to take his place." - C.G., Homeowner

★★★★★ "The Mavromihalis team is a force. I know this because I have worked with them on 3 transactions in the past 2 decades. Thorough to the point that you would think they were actually the sellers of the listed property. That said, I truly believe that the more closely one follows their sage advice, the more successful the outcome. In prepping the home to be listed, whether in deferred maintenance or small renovations/styling, the Mavromihalis team offered nuts and bolts suggestions that were, each and every one, intentional. In this way, they started creating a unique story for our property the minute they were brought on board. Thoughtfully crafted, our property’s story ended up being integral to the entire listing; it informed the literature, the staging, the demographic targeted... everything. What a cohesive product they deliver every time." - VW, Designer

★★★★★ "Steven Mavromihalis listed my San Francisco property, and he and his team guided me through to completion of the sale process, which was unexpectedly protracted a few months to obtain regulatory clearance for a buried oil tank. The team was experienced and knew exactly the right levers to pull for expediting the process. Steven engaged the best people for each task, and the team's attention to detail and follow-up is second to none. True professionals all. " - BC

★★★★★ "Steven has helped our family purchase and sell several homes and has delivered exceptional results. He has a high sense of urgency and a tremendous work ethic, and is passionate about protecting the long-term interests of his clients. " - Michael J. Mendes
