A 501(c)(3) nonprofit medical practice, Dr. Yang's Family Care operates in San Diego's San Carlos neighborhood at 6280 Jackson Drive, Suite 8, within the 92119 ZIP code. The clinic's nonprofit model directs revenue back into patient services rather than physician profit, and rehabilitation needs from its patient panel connect to physical therapy providers across San Carlos — PhysioFixx Physical Therapy on the San Carlos commercial strip handles sports-injury and post-surgical recovery programs for patients referred from primary care. Jackson Drive runs through the commercial heart of San Carlos, paralleling Lake Murray Boulevard and serving the residential neighborhoods that stretch between Cowles Mountain and Lake Murray to the east. The 501(c)(3) designation means the clinic can accept charitable contributions and grant funding to subsidize care for uninsured or underinsured patients — a mechanism that supplements Medi-Cal and Medicare reimbursement in a ZIP code where household incomes range widely between the Lake Murray hillside homes and the apartment complexes along Jackson Drive. Primary care in San Carlos sits between two major medical systems: Kaiser Permanente's Zion campus to the west in Allied Gardens and the Grossmont Center medical offices on the La Mesa border to the east. Acute and after-hours care needs that exceed the clinic's office capacity connect to walk-in urgent care resources nearby, and Perlman Clinic La Mesa in Grantville provides same-day evaluation for patients of all ages along the Mission Gorge Road corridor. The 92119 ZIP code covers San Carlos and portions of Del Cerro, drawing a patient base from the suburban residential tracts that surround the Navajo Road and Jackson Drive commercial district.
