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, and currently serves at the Vice Chair of the Contra Costa County Board of Supervisors.
Diane’s priorities are to actively represent all parts of the District; ensure fiscal accountability and transparency; provide public safety and needed services for our most vulnerable in East Contra Costa County; protect and conserve our natural resources including our precious Delta; promote economic development and job creation for East Contra Costa County residents; and find solutions to reduce traffic and congestion to improve the quality of life for the residents she serves.
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 grandsons. She raised her three sons in Oakley and has called Contra Costa County home for most of her life.
