About DHS

about dhs  

The Los Angeles County Department of Health Services (DHS) is the second largest public health care system in the nation.  Through its integrated network of 19 community-based clinics and four hospitals, DHS treats approximately 570,000 unique patients a year, employs over 20,000 staff, and has an annual operating budget of $4 billion. The Department’s partnerships with private, nonprofit clinics expands access to quality primary care services at over 100 additional sites across the County of 10 million residents.  DHS hospitals are training sites for physicians completing their graduate medical education, and DHS clinics are models of patient-centered health care.  Through its Housing for Health division, DHS is reducing chronic homelessness through sustainable, supportive housing projects along with other innovative programs to improve the health of vulnerable populations.


Our mission is to ensure access to high-quality, patient-centered, cost-effective health care to Los Angeles County residents through direct services at DHS facilities and through collaboration with community and university partners.
