Southern Indian Health Council's Alpine clinic at 4058 Willows Road in Alpine houses the practice of Nicole Gullick, MD, within a 10-acre tribal health campus serving the Kumeyaay Nation and surrounding communities. Incorporated as a nonprofit in 1982, SIHC operates under IHS affiliation (NPI 1346247947) and provides integrated medical, dental, pharmacy, and behavioral health services — a full-spectrum dispensary model that coordinates outpatient prescriptions with Albertsons Pharmacy on Alpine Boulevard for patients who fill medications off-campus. The Willows Road facility sits near the Viejas Casino & Resort corridor, giving patients along the I-8 and Willows Road interchange a single-stop option for primary care, substance-use treatment, and community health education. SIHC accepts most PPO and HMO plans, TRICARE, Medicare, and Medi-Cal, extending access beyond tribal enrollment to the general public throughout Alpine and the surrounding East County backcountry. Pediatric and family medicine referrals within the Alpine Boulevard corridor connect patients to specialized youth oral health services at Alpine Pediatric Dentistry in the 1620 Alpine Boulevard medical complex. The clinic's highest-complexity services include medication-assisted substance-use treatment, integrated behavioral health crisis intervention, and chronic disease management for diabetes and cardiovascular conditions prevalent in rural San Diego County populations.
