San Diego County HHSA South Region in Chula Vista operates the South Region Live Well Center at 690 Oxford Street, delivering CalFresh enrollment, Medi-Cal eligibility determinations, CalWORKs cash assistance, and General Relief processing for South Bay residents. The center's behavioral-health referral pipeline connects applicants experiencing mental health crises with outpatient providers such as Stars Therapy Services under county-funded Medi-Cal managed care. Three distinct divisions share the campus: the Family Resource Center administering self-sufficiency programs, the Public Health Center providing immunizations and STD/HIV screenings, and Public Consulting Group managing CalWORKs employment-services case management. The Public Health Center's immunization clinic serves children and adults without coverage, Medi-Cal participants ages 0–18, and Alaska Native or American Indian patients ages 0–18, with walk-in flu vaccines available regardless of insurance status. Senior-services coordination extends to the Aging & Independence Services division and programming at facilities such as Norman Park Senior Center, where the county facilitates nutrition and wellness activities for adults over 60. The STD clinic operates a separate schedule within the Oxford Street campus, offering chlamydia, gonorrhea, syphilis, hepatitis, and herpes testing alongside free HIV screening and Mpox vaccination under CDC guidelines.
