District 3 Supervisor Ray Mueller
Meet Ray


In 2022, Supervisor Ray Mueller was elected to represent District 3 on the San Mateo County Board of Supervisors. In his first year on the job, Ray and his staff have rolled up their sleeves and dived into serving his community. Together they have responded to unprecedented challenges brought from winter storm systems and tackling public health safety issues facing the District.  Supervisor Mueller has taken the lead in repairing coastal infrastructure and building healthy and safe farmworker housing. 

Ray also serves on numerous boards of directors in his role for the County, including SamTrans, the Caltrain Peninsula Corridor Joint Powers Board, Peninsula Clean Energy, the San Mateo County Transit District and County Transportation Authority, Housing Our People Effectively, the San Mateo Health Commission, One Shoreline, the FEMA Emergency Food & Shelter Program Local Board and more. 

Prior to his election to the Board of Supervisors he served 10 years as a City Councilmember, gaining re-election 3 times. Supervisor Mueller is a graduate of University of California, Hastings College of the Law and UC Berkeley and holds a certificate in Diversity and Inclusion from Cornell University’s online platform, eCornell.  A commitment to public service is shared in Ray’s household, as his wife and high school sweetheart Kristen, was named public school administrator of the year in the San Mateo and San Francisco counties in 2015. Together they are raising their two school aged children and feel blessed to live in San Mateo County.
