    Redwood City — Noelia Corzo and Ray Mueller were sworn in this morning to the San Mateo County Board of Supervisors.

    Both received standing ovations as they were sworn in by their respective family members in the Board Chambers on the County Center campus in downtown Redwood City.

    Together, they represent the largest change on the five-member Board in a generation; the last time two new members were sworn in at the same time was 1993. Both won run-off elections in November.

    Corzo was sworn in by her mother, Aura Ester Solorzano, and her 11-year-old son, Mike Alvarado-Corzo. She represents District 2, which includes the cities of San Mateo and Foster City and much of Belmont.

    Corzo campaigned on a message of bringing her professional experience as a social worker “who knows exactly where our neighbors fall through the cracks” and her personal experience as a single mom “who understands the importance of access to high-quality childcare, healthcare and education.”

    Corzo is a San Mateo resident who grew up in the city’s North Central neighborhood. She is currently the only woman on the Board of Supervisors and the first Latina to serve on the Board in the County’s 158-year history. She formerly served on the San Mateo-Foster City School District Board of Trustees.

    Mueller was sworn in by his wife, Kristen Shima, and children Max Mueller, 17, and Elle Mueller, 13. He represents District 3, which includes the cities of Atherton, Half Moon Bay, Pacifica, Portola Valley, Woodside and part of Belmont, along with large unincorporated areas.

    A resident of Menlo Park, Mueller campaigned on a message of addressing challenges such as affordable housing, investment in coastside infrastructure and environmental stewardship, among other issues.

    He has pledged to do “impactful work on behalf of San Mateo County District 3; work which will make a difference to our quality of life, our safety, our economy, our environment and our future.” He previously served on the Menlo Park City Council.

    Mueller succeeds Don Horsley as District 3 representative; Corzo succeeds Carole Groom as District 2 representative. Both Horsley and Groom were termed out of office.

    At the same meeting, Supervisor Dave Pine was elected president of the Board of Supervisors for the upcoming year.

    Pine, who won a special election in 2011 and has been subsequently reelected three times, said his goal will be to “facilitate a highly effective and productive culture among the Board of Supervisors that will enable us to make the best decisions possible for the good of the county.”

    With District 4 Supervisor Warren Slocum, who was elected as vice president for 2023, and District 5 Supervisor David J. Canepa, the Board of Supervisors oversees a $4 billion annual budget that provides safety net, public safety and other services. The Board also establishes policies that govern the unincorporated areas of the county.

    Members of the Board also serve on a number of local and regional boards and commissions.
