About Cynthia Peterson

Cynthia is an award-winning REALTOR® who focuses on providing the highest quality service and delivering exemplary results for each client. To achieve optimum results in the Bay Area’s competitive residential markets, buyers and sellers need a skilled communicator working with drive and enthusiasm. Cynthia is that agent. Her values of integrity, flexibility, resourcefulness, creative thinking, and attention to detail make the process of buying or selling a home seamless and efficient, always with the goal of surpassing client expectations. For Cynthia, being a successful real estate professional is much more than helping people buy and sell homes — it is connecting with the community, forging relationships, and aiding clients to fulfill their version of the American Dream.

Cynthia’s desire to serve clients comes from a deep-rooted love of volunteerism. During a gap year after high school, Cynthia became an AmeriCorps volunteer where she taught conflict-resolution skills and provided inner-city youth a safe place to be children. After college, she joined the AmeriCorps chapter in North Lake Tahoe, working at Tahoe SAFE Alliance. The opportunity to contribute to a greater good in such a beautiful environment is what made her fall in love with the California lifestyle. She continues to serve Habitat for Humanity and Food Bank of Contra Costa & Solano County. She also proudly serves on the Governing Board for the Women’s Council of REALTORS®, Contra Costa Network.

When not researching and pursuing the next deal for her clients, Cynthia can be found hiking with her husband Mark and their Ausky pup, traveling, and camping. As a resident of downtown Martinez, Cynthia loves exploring the multitude of amazing eateries and locally owned shops that Martinez has to offer.

Headquartered in Santa Rosa, CA

Founded in 1975, Canine Companions for Independence is a non-profit organization that enhances the lives of people with disabilities by providing highly trained dogs and ongoing support to ensure quality partnerships.

The assistance dogs aren’t just the ears, hands and legs of their human partners. They’re also goodwill ambassadors and often, their best friends. They open up new opportunities and new possibilities and spread incredible joy. We unite people with dogs in a powerful program that leads to greater independence and confidence.


Food Bank of Contra Costa & Solano

We believe there’s strength in numbers and in working together. We are members of Feeding America and California Association of Food Banks. Nearly 200 Partner Agencies have joined us to serve families in Contra Costa and Solano counties at soup kitchens, food pantries, after-school programs, snack programs and other service sites.

Through our relationship with Feeding America, the Food Bank service area spans 18 counties covering over 38,000 square miles, but 16 of these counties are served by five partner distribution organizations (PDOs); the Food Bank only serves Contra Costa and Solano counties. In general, a PDO operates within a defined portion of the food bank service area and performs all of the primary food bank responsibilities, including the procurement and distribution of food and partnership with member agencies.
