Health and Human Services Agency

The Shasta County Health and Human Services Agency (HHSA) partners with communities to protect and improve the health and well-being of Shasta County residents. Established in 2006, the HHSA is organized into four branches: Children’s Services, Adult Services, Public Health, and Economic Mobility, with a centralized administration. The HHSA promotes optimal health for all. The frail, the abused, the mentally ill and those without resources look to the HHSA for services and resources to meet their basic needs, and to protect their health and safety. This transformation improves efficiency, avoids unnecessary duplication of effort, encourages collaboration among programs and organizes the HHSA’s services to be more responsive to the needs of the public.

The Public Health Branch focuses on community-wide prevention of communicable disease, chronic disease, injury, substance abuse, family violence, and lead poisoning. Public Health helps the community develop policies and support community environments that encourage healthy behaviors. It promotes nutrition and physical activity, healthy aging, worksite wellness and healthy communities. Public Health is also where the HHSA’s emergency response unit is headquartered, and its laboratory provides testing services for Shasta and numerous other Northern California counties.
