Operated by Family Health Centers of San Diego—a federally qualified health center founded in 1970 and designated a Health Center Quality Leader by HRSA—the Downtown Family Health Center at Connections occupies Sixth Avenue in downtown San Diego. The Connections clinic integrates primary care, behavioral health, and substance-use treatment under one roof, delivering medication-assisted treatment with buprenorphine and naltrexone alongside the acute-care triage available at nearby UC San Diego Health Express Care. FHCSD's sliding-fee scale and Medi-Cal/Medicare acceptance serve a patient population that is 91 percent low-income and 29 percent without insurance coverage, with eligibility navigators embedded in the intake workflow. On-site optometry, podiatry, and dental services create a medical-home model that reduces referral attrition for populations who also receive general-practice care at Winfield Dental Group, Inc. in the surrounding blocks. Cognitive behavioral therapy, dialectical behavioral therapy, and trauma-informed counseling are delivered through the same facility that manages chronic-disease panels for diabetes, hypertension, and HIV, consolidating behavioral and medical records into a single FQHC electronic health record.
