Hon. Diane Burgis

Supervisor Diane Burgis proudly serves the 230,000 residents of Contra Costa County’s 3rd Supervisorial District — the largest of the five districts - covering Antioch, Bethel Island, Brentwood, Byron, Unincorporated Clayton, Discovery Bay, Knightsen, and Oakley in East Contra Costa County; and Blackhawk, Diablo and Tassajara Valley in the southern portion of the district.

She was elected to office in 2016 and re-elected to her second term with 67.74% of the vote in March 2020. In January 2021, she was appointed Chair of the Contra Costa County Board of Supervisors.

Supervisor Burgis serves on 30 Board of Supervisor and regional committees, including as Chair of the Airports Committee, Legislation Committee, and the Open Space/Parks & East Bay Regional Parks District Liaison Committee, and as a newly appointed alternate to the San Joaquin Joint Powers Authority.

Diane’s priorities are to work with and support our county health officer to get the coronavirus under control, move the County toward economic recovery for all residents and businesses, enhance mental health crisis response, address racial justice and inequality, protect the Delta, and at long last, provide sustainable fire protection services to all areas of the County.

Prior to being elected to the Contra Costa County Board of Supervisors in 2016, Diane served as a trustee on the East Bay Regional Parks District Board, a member of the Oakley City Council, and as the Executive Director of Friends of the Marsh Creek Watershed.

Diane is a single mother and proud grandmother of two. She raised her three sons in Oakley and has called Contra Costa County home for most of her life.
