District IV Supervisor Karen Mitchoff

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.

We live in an ever-evolving economy with constant change in community needs, and serving constituents in District IV is my #1 Priority. I encourage you to contact me directly with any questions or concerns you might have.


I look forward to seeing you around the community!
