Welcome to the State of California 


Dr. Ron ChapmanAs a family doctor and public health physician I have had the honor to care for Californians in clinics, hospitals, and communities. I understand the importance of health and wellness, and the devastating effects of disease. 

I am privileged to be the Director of the California Department of Public Health which has professional staff whose expert work is nationally and internationally recognized. Together, we are dedicated to preventing disease and injuries, and protecting your health and safety. 

The California Department of Public Health website is filled with information about important public health issues, news about our programs, and many other valuable resources. I invite you to browse these pages and learn how our department fulfills its mission of optimizing the health and well-being of the people in California. 

Public health touches all of our lives in many ways, each and every day. The work of our department, done in tandem with partners at the federal, state and local levels, affects everyone in the state -- from newborns to seniors. Our work is accomplished by promoting pre-natal care, providing immunizations, educating families to use car seats, promoting anti-tobacco policies, regulating healthcare facilities, maintaining safe drinking water, supporting nutrition education, preparing for disasters, conducting disease outbreak investigations … and much, much more. 

We share a dedication to public health and public service, which we display through our core values: collaboration, competence, equity, integrity, respect, responsibility, trust and vision. 

As Director of the California Department of Public Health and State Health Officer, I look forward to working within your communities to improve the health of all people in California.
