District 4 Supervisor Karen Mitchoff

DUE TO THE HEALTH ORDERS, MY OFFICE IS CLOSED AND STAFF ARE WORKING REMOTELY. PLEASE CALL 925-521-7100 OR SEND AN EMAIL TO SUPERVISORMITCHOFF@BOS.CCCOUNTY.US WITH ANY QUESTIONS OR CONCERNS. WE ARE COMMITTED TO CONTINUE PROVIDING SERVICE TO RESIDENTS OF DISTRICT IV.

Hello and welcome to the District IV website! As your County Supervisor, I was elected to serve the diverse communities of Clayton, Concord, Pleasant Hill, part of Walnut Creek, and the unincorporated Contra Costa Centre.

District IV is located in the beating heart of Contra Costa County. We have seen great transformation in our communities in a few short years, as innovation, prosperity, and new residents join us in the shadow of Mt. Diablo. Mindful of these developments, it is my core focus to build policies that best serve you, my constituents in District IV, and our neighbors across Contra Costa.

I am committed to better connecting the people of Contra Costa County with the vital services of government, and advocating for policies that will help our communities grow and prosper. 

I look forward to hearing from you.

Karen Mitchoff
