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.
