From City Hall to the front lines of crisis response, Ray Mueller is a proven leader fighting for safe, strong San Mateo County communities.

Supervisor Ray Mueller was elected to the San Mateo County Board of Supervisors in 2022 with a clear mission: to make our communities safer, more resilient, and better prepared for the future. Representing District 3 - from Pacifica to the coastal bluffs of Half Moon Bay and Pescadero, to the forested hills of Portola Valley and Woodside and the bayside neighborhoods of Menlo Park, Atherton, Emerald Hills, San Carlos, and Belmont—Ray is a leader who doesn’t just sit in an office; he is on the front lines during every storm and crisis. He has worked hard to improve our infrastructure, fund long needed programs, and put in place policies that make a difference.

A former two-term Mayor, ten year City Councilmember, Ray brings a unique professional background to the Board. Prior to joining the Board of Supervisors Ray worked as an attorney specializing in the emergency response and services sector, giving him a deep understanding of how to navigate bureaucracy to get help to residents when they need it most. 

Ray and his wife Kristen, a local school Principal, have raised their family in the community they love. Ray’s work is driven by a simple goal: ensuring a secure and stable future for every family in San Mateo County.
