Jershonda F. Hartsfield, MD, FAAP practices pediatric medicine in Santee at Sharp Rees-Stealy on Cuyamaca Street, where she also serves as Chief of Pediatrics at Sharp Mary Birch Hospital for Women & Newborns. Dr. Hartsfield earned both a dental degree from UCLA School of Dentistry (2001) and her medical degree from the David Geffen School of Medicine at UCLA (2002), then completed pediatric residency at Children's Hospital of Orange County in 2005 — a dual-credential background that informs the oral-health screenings she integrates into well-child visits alongside vision referrals to Santee Family Optometry on Mission Gorge Road. Trilingual in English, Spanish, and Tagalog, Dr. Hartsfield addresses a broad clinical range including ADHD, asthma, eczema, and pediatric diabetes for families across Santee, El Cajon, and Chula Vista. Newborn metabolic panels and CBC draws ordered through her second-floor office process downstairs at Sharp Rees-Stealy Santee Laboratory on the first floor, with results feeding directly into the Sharp system-wide electronic health record. Her highest-acuity neonatal assessments include Barlow and Ortolani hip-dysplasia screening, critical congenital heart defect pulse-oximetry protocols, and bilirubin monitoring via transcutaneous bilirubinometry for jaundice-risk stratification in the first 72 hours of life.
