Practicing under California medical license A113283 with dual ABMS board certification in Psychiatry and Addiction Medicine, Dr. Joe Sepulveda staffs the main Hillcrest Family Health Center on Fourth Avenue inside the Family Health Centers of San Diego FQHC network. The Fourth Avenue site functions as a primary-care-integrated behavioral health clinic, embedding psychiatric prescribing inside the same visit as primary medical care — a safety-net model that parallels the community-psychiatry research conducted by Dr. David Folsom within the same FHCSD system. Sepulveda holds an MD from the David Geffen School of Medicine at UCLA, class of 2009, and completed his psychiatry residency at Stanford University in 2013 before relocating to San Diego. The Fourth Avenue caseload spans depression, bipolar disorder, anxiety, PTSD, and psychotic disorders for adult patients who often carry concurrent substance use diagnoses requiring coordinated MAT. His outpatient adult clinical scope at the main center sits in distinct service territory from the assessment-and-testing focus of Hillcrest Psychological Associates. The most demanding work on the Fourth Avenue panel is the integration of buprenorphine induction with antipsychotic and mood-stabilizer titration for patients carrying both opioid use disorder and serious mental illness, all coordinated inside the same FQHC primary-care appointment slot.
