Who we are

Regional Public Health Office is housed within the California Department of Public Health. We are dedicated to improving communication and coordination across all regions of California. Our goal is to effectively address emerging public health concerns by promoting unity and safeguarding community well-being throughout the state. We do this by building upon successful inter-agency collaboration. We aim to accomplish our goals by elevating information about statewide priorities and offering technical assistance to local health jurisdictions with limited resources.


Our mission is to strengthen the infrastructure of public health, facilitate active communication, and collaborate with state and local partners to advance regional capacity.


We envision a healthy California achieved through trusting and collaborative regional public health partnerships.​

​​Regional Public Health Office Regions​

 The Regional Public Health Office map was created in collaboration with health officials from various areas in California during the COVID-19 response. Additionally, we carefully considered and incorporated valuable feedback from local health partners. RPHO has a dedicated team that works closely with these regions to ensure seamless coordination, effective communication, data analysis and efficient operations.​

The regions we cover include Rural North, Greater Sierra Sacramento, Bay Area, Central California, Southern California and Los Angeles. Each region comprises specific counties and cities. This strategic approach enables us to tailor our efforts to meet the unique needs of each area, providing robust support to their communities.
