Sung W. Song, MD - Sharp Rees-Stealy Santee provides board-certified family medicine from the second floor of the 86,000-square-foot Cuyamaca Street medical campus. Trained at Hahnemann University School of Medicine — now Drexel University College of Medicine — class of 1995, Dr. Song treats conditions from diabetes and hypertension to gastroesophageal reflux within a multispecialty system where prescriptions fill one floor below at Sharp Rees-Stealy Santee Pharmacy. His clinical scope spans chronic-disease management, obstructive sleep apnea evaluation, and cardiac-arrhythmia screening for East County patients along the Cuyamaca Street corridor. Lipid panels, retinal-screening referrals, and hemoglobin A1C monitoring feed through Sharp's integrated network, the same coordinated model that connects primary care to vision providers such as Santee Family Optometry on Mission Gorge Road. Advanced in-office diagnostics include 12-lead electrocardiograms and spirometry screening, with results integrated into Sharp's system-wide electronic health record for real-time specialist coordination across 22 locations.
