McGill University-trained pediatrician Stephen H. Carson, MD practices pediatric primary care and pediatric pulmonology with Children's Healthcare Medical Group at 550 Washington Street Suite 300, board-certified in pediatrics since 1980. Complex endocrine co-management for pediatric patients including growth hormone deficiency, early puberty, and type 1 diabetes flows to Children's Healthcare Pediatric Endocrinology inside the same practice network. Dr. Carson graduated from McGill University Faculty of Medicine in 1976, completed pediatric residency at Boston Children's Hospital through Harvard Medical School from 1976 to 1979, and served as Chief Resident in Pediatrics at the UC San Diego School of Medicine in 1980. His published research includes sudden infant death syndrome apnea program evaluation in Pediatrics (1986) and a Pediatric Annals case series on fever and oral lesions in young children. Adolescent patients aging out of pediatric pulmonology transition to adult pulmonologists such as Dr. Jess J. Mandel, MD for ongoing asthma, cystic fibrosis, and sleep-disordered breathing management. The highest-complexity work in this panel is longitudinal care of medically complex children with chronic respiratory conditions, including technology-dependent patients on home oxygen, nocturnal ventilation, or airway clearance regimens, provided in Spanish and English.
