Learn more about the Orange County Health Care Agency

Clayton Chau, M.D., Ph.D Director


The Health Care Agency is a regional provider, charged with protecting and promoting individual, family and community health through coordination of public and private sector resources. HCA's service environment is complex, with 180 different funding sources and over 200 State and Federal mandates. The mandates under which HCA operates require the County to provide for, or to regulate, certain health services. Many also carry specific requirements for staffing, operations, claiming and record keeping.

Many of HCA's services are preventive in nature and therefore are not readily apparent to the public. Some examples of services include food protection, hazardous waste regulation, water quality monitoring and pollution prevention, mental health services, alcohol and drug abuse services, preventive health services for the aging, healthcare for incarcerated individuals, communicable disease control, child health and disability program, immunizations, public health field nursing and public health clinics.

Who We Serve

Our ultimate client is the entire County population. While providing direct services to individual clients or patients, the Agency's primary focus is to protect and promote the health and safety of the community as a whole. As we know, Orange County is continuing to grow and become more diverse. Over the next decade, teens and older adults will become Orange County's fastest growing population sub-groups. The Health Care Agency is continually planning in anticipation of these changes so that our services meet the needs of the community.
