Concentrating Family Health Centers of San Diego's specialty-care services at 4065 Third Avenue, the Hillcrest Family Health Center on Third Avenue runs mental health, substance use disorder treatment, dental care, and HIV case management under one roof. Medications for Addiction Treatment programs operate on-site for opioid use disorder using buprenorphine and naltrexone protocols, with psychiatric stabilization handed off to specialty groups like Advanced Psychiatry Associates when dual-diagnosis complexity exceeds primary care scope. The dental clinic handles preventive cleanings, fillings, and extractions on a sliding scale tied to household income. HIV-positive patients receive linkage to care, treatment adherence support, and benefits navigation through a dedicated case management team coordinating with AHF Wellness Center - San Diego for specialty HIV medical management. The mental health team delivers individual therapy, group therapy, and psychiatric medication management for Medi-Cal beneficiaries throughout the corridor. Co-located dental and behavioral health under FQHC funding makes this one of the few sites in central San Diego where a patient can address opioid recovery, untreated periodontal disease, and depression in the same building on the same visit.
