Pediatric care from birth through adolescence anchors Dr. Tammy Dong's Chula Vista practice in the Third Avenue district at 678 3rd Ave, where her board certification covers developmental screening and acute-illness triage. Her University of Illinois College of Medicine degree and UC San Diego Medical Center pediatric residency equip the practice for complex diagnostic workups, with behavioral screening referrals routing through Stars Therapy Services when developmental milestones signal the need for speech, occupational, or ABA intervention. Mandarin-language consultations extend access to Chula Vista's Mandarin-speaking families, adding a linguistic resource uncommon among South Bay pediatric practices. Well-child protocols cover newborn metabolic screening, lead-level assessment, and adolescent sports physicals, with annual vision screening referrals coordinating alongside Villa Optometry for comprehensive pediatric eye exams. Her Rady Children's Hospital-San Diego affiliation supports tertiary pediatric transfers for cases requiring PICU admission, pediatric surgical consultation, or advanced diagnostic imaging beyond the outpatient setting.
