Message from Director Dr. William Walker

As the Director of Contra Costa Health Services (CCHS) and the Health Officer for Contra Costa County, my job is to lead the department that cares for the most vulnerable people in our county and improves the health of all who live here. Communities must have the conditions for good health, including safe drinking water, clean restaurants, control of communicable diseases, access to health care and a reliable emergency medical system. CCHS provides all of these services and more.

We prepare for and respond to health emergencies like flu outbreaks, whooping cough and hazardous materials incidents. We run the Contra Costa Regional Medical Center, eight Health Centers, the Public Health laboratory, treatment for alcohol and drug addiction, and services for people who are seriously mentally ill or homeless. This brochure gives you a taste of the broad scope of our work in Contra Costa Health Services and our inter-related goals of Service Excellence and Reducing Health Disparities. You can get more information about our progress and services on our website at

Thank you,
William Walker, MD
