San Ysidro Health Alpine Family Medicine at 1620 Alpine Boulevard in Alpine is a Federally Qualified Health Center operating under NPI 1770124315 as part of San Ysidro Health, a nonprofit founded in 1969 that now manages over 50 program sites and serves more than 161,000 patients across San Diego County. The Alpine Boulevard suite houses family medicine, internal medicine, behavioral health, and chiropractic departments within the same medical complex as Comprehensive Medicine on Alpine Boulevard, creating a multi-provider corridor for East County primary care. Sliding-scale fee structures and Medi-Cal enrollment assistance ensure Alpine and Harbison Canyon residents without commercial insurance can access preventive care, chronic disease management, and CDC-listed STI screening. The clinic's behavioral health team integrates substance-use counseling and psychiatric evaluation into standard family medicine visits, reducing referral lag for patients with co-occurring conditions. Primary care physicians at this location coordinate pediatric and geriatric referrals with providers including Larry Marshall, MD on Lakeshore Drive for specialist consultations across the Lakeside-Alpine service area. Highest-complexity services include PrEP navigation, medication-assisted opioid treatment, and multi-visit chronic disease management protocols for uncontrolled diabetes and hypertension in medically underserved East County populations.
