The Los Angeles County Department of Public Health (Public Health) works to protect health, prevent disease, and promote health and well-being for everyone in Los Angeles County. Los Angeles County is the largest county in the United States: home to over 10 million diverse residents and a travel destination for millions each year. One of the Department’s top priorities is to advance health equity through community-based collaborations with a wide range of partners to support policies, practices, and programs that lead to healthier environments. Public Health maintains a broad portfolio of essential programs and services including 14 Public Health Centers located throughout LA County.

The Department provides free and/or low-cost services to those without insurance or a regular health care provider, promotes healthy behaviors, advocates for access to health care coverage and a regular source of care, or medical home, ensures safe drinking water, promotes childhood vaccinations, and provides sexual health education to ensure the health of all residents. Additionally, Public Health Nurses make home visits to families and to first-time pregnant women, Epidemiologists investigate the sources of disease outbreaks, and Environmental Health Specialists ensure safe food, water, and housing.

We encourage you to join the over 4,000 Public Health professionals working to improve health and wellness across Los Angeles County. Please explore our internship and volunteer opportunities to discover the many ways that you can work in Public Health.
