Katherine M. Miller
January 2019 - January 2023


Kathy Miller was elected to the Board of Supervisors in June 2014, sworn in on January 5, 2015, and served as Board Chair in 2015 and 2020. In June 2018, she was re-elected to the Board of Supervisors and continues to serve District 2, until she terms out in December 2022.

She currently represents San Joaquin County in many capacities, including as a member of the San Joaquin General Hospital Health Care Services Review project, Hospital Joint Conference Committee, San Joaquin Continuum of Care, Health Services Committee/Health Plan of SJ, and the SJ Council of Governments. In addition, Kathy continues her leadership on regional water issues, serving on the Five Delta Counties Coalition, the San Joaquin Area Flood Control Agency and the Sacramento-San Joaquin Delta Conservancy.

For more than three years, Supervisor Miller led the countywide Homelessness Task Force, which was merged into an expanded Continuum of Care in 2019. She has also led the county’s Children & Youth Task Force, currently focused on developing recommendations for one-time investments of ARPA (COVID-recovery) federal funding. This community-building work includes diverse representation, such as non-profit service providers, county departments, municipal partners, school districts and the business community.

Prior to her election to the San Joaquin County Board of Supervisors, Supervisor Miller served on the Stockton City Council, 2009 – 2014, with four of those years as Vice Mayor, and emerged as a strong voice for fiscal responsibility and open, transparent and accountable local government.

During her years as an elected official, Miller has also represented Stockton residents on the Delta Protection Commission, Stockton Convention & Visitor’s Bureau and the Library & Literacy Foundation of San Joaquin. In addition, she has held leadership positions and rose to the rank of Second Vice President of the statewide League of California Cities.

After growing up in Southern California, Kathy and her family moved to Stockton in 1997, after living in the Seattle area for almost 20 years. Once in Stockton, Kathy established and operated her own interior design business, Bonniebrook Interiors, and volunteered with First Night Stockton, the San Joaquin Aids Foundation and as a cuddler in the neonatal intensive care nursery of San Joaquin County General Hospital. In 2004, Kathy became the Executive Director of the Downtown Stockton Alliance, providing security, maintenance, economic development, special events and advocacy to the downtown business and property owners until her election to the Stockton City Council in 2008. Kathy and her husband, Karl, have been married almost 45 years, have three grown children and six grandchildren.
