Pediatric primary care at Sharp Rees-Stealy's La Mesa location draws on Dr. Li-Wen Jen's Massachusetts General Hospital residency training, a Harvard-affiliated program that anchored her clinical foundation in evidence-based pediatrics. Pediatric vision screenings at the Grossmont Center Drive campus identify acuity and alignment issues early, with ophthalmologic referrals connecting through La Mesa providers such as Giles Optometry for comprehensive pediatric eye exams. She earned her medical degree from National Taiwan University College of Medicine in 1986 and completed a transitional-year internship at the University of Maryland Medical Center before her Harvard-affiliated residency. Her clinical panel covers well-child examinations, vaccine administration per the CDC immunization schedule, and management of common childhood conditions from otitis media to atopic dermatitis. Musculoskeletal complaints in active pediatric patients—growth-plate-related pain, postural asymmetry, and sports-related strains—extend the practice's scope into collaborative care with Awesome Family Chiropractic in La Mesa for pediatric spinal and joint evaluation. Her most complex clinical assessments involve evaluation of failure-to-thrive infants using standardized growth-velocity calculations and nutritional biomarker panels to distinguish organic from non-organic etiologies.
