Sharna B. Shachar, MD operates a board-certified internal medicine practice in Chula Vista's Broadway corridor at 525 H Street under a Professional Medical Corporation structure. Her adult primary care focus covers chronic disease management for arthritis, diabetes, and hypertension, and complex cases requiring inpatient evaluation coordinate through her privileges at Scripps Mercy Hospital Chula Vista on Medical Center Drive. She earned her medical degree from Baylor College of Medicine in 1991, completed her internal medicine residency at UCLA-VA Greater Los Angeles from 1991 to 1994, and has maintained a Chula Vista practice since 1997 under California medical license A51402. Consultations in Hebrew, Spanish, and English serve the multilingual patient base along the H Street and Broadway commercial node near Chula Vista Center Mall and Costco. Musculoskeletal complaints presenting alongside her internal medicine caseload — including cervical strain, lumbar pain, and joint stiffness — triage to manual-therapy providers such as Clear Chiropractic for spinal and extremity assessment. Comprehensive internal medicine workups include multi-system evaluation combining renal-function panels, thyroid-cascade testing, hepatic enzyme analysis, and lipid-panel-driven cardiovascular risk stratification for patients managing concurrent metabolic and autoimmune conditions.
