Tufts-trained family physician Melissa Campos, MD practices in Chula Vista's Third Avenue Village through San Ysidro Health, a federally qualified health center at 678 Third Avenue. Her full-spectrum practice covers chronic disease management, acute-care triage, and obstetric care, with integrated behavioral health screenings that connect to Chula Vista's community mental health network through South Bay Guidance Center. A Yale University graduate, she earned her medical degree from Tufts University School of Medicine in 2014 and completed her family medicine residency at Scripps Mercy Hospital, where she now serves as faculty for the Scripps Family Medicine Residency Program. San Ysidro Health operates as a federally qualified health center along the Third Avenue corridor, providing medical, dental, and behavioral health services with bilingual Spanish-English consultations for the underserved South Bay community. Beyond standard primary care, her clinical scope includes in-hospital newborn assessments at Sharp Chula Vista Medical Center and nursing-home rounding, with musculoskeletal complaints triaged through manual-therapy referrals to Gerken Family Chiropractic. The residency teaching model trains incoming physicians in procedures including IUD insertion, joint injections, and skin-biopsy techniques under faculty supervision at the Third Avenue clinic.
