Family medicine physician Dr. Zachary Thomas practices at Family Health Centers of San Diego on El Cajon Boulevard in San Diego's College Area, 5454 El Cajon Boulevard, 92115. NPI 1326453119 registers him under family medicine taxonomy with California license A145023, and his practice operates within the FHCSD network — a federally qualified health center system that provides primary care regardless of a patient's insurance status or ability to pay. The FHCSD model accepts Medicare, Medi-Cal, commercial insurance, and uninsured patients on a sliding-fee scale, a structure that serves the economically diverse College Area population along the El Cajon Boulevard commercial corridor near SDSU. Musculoskeletal and postural complaints from his patient panel connect to chiropractic providers across the College Area, and Family Connection Chiropractic in the College Area handles spinal evaluation and adjustment for patients needing conservative musculoskeletal care. His treatment data shows case volumes in constipation management, upper respiratory infection, and the chronic disease monitoring — diabetes, hypertension, coronary artery disease — that defines a high-volume family medicine panel in an urban safety-net setting. El Cajon Boulevard through the College Area carries the densest stretch of independent medical clinics, international restaurants, and small retail in San Diego's eastern corridor, running east from SDSU toward La Mesa. Vision screening and routine eye exams from his panel coordinate with optometric referrals across the 92115 service area, and KDT Optometry in the College Area handles both pediatric and adult eye examinations. Family Health Centers of San Diego operates more than 70 sites countywide, and the El Cajon Boulevard location positions Dr. Thomas within the organization's eastern San Diego service network.
