John Duncan, M.D. is board-certified in Pediatrics and in Pediatric Endocrinology. He has practiced for 24 years and specializes in metabolic diseases, endocrine problems and diabetes in children. In the Melbourne/Palm Bay area since 1986, Dr. Duncan holds privileges at Holmes Regional Medical Center, where he remains the only pediatric endocrine sub-specialist for newborns, infants, children and adolescents. At HRMC, he remains the Pediatric Diabetes Consultant to the hospital’s nationally-recognized Diabetes Center. Part of his office practice includes provision of Pediatric Endocrine Consultative Services to the Florida Children’s Medical Services system, a role he began while still an assistant professor at the University of South Florida in 1982. This system provides care for children and adolescents with chronic medical conditions. These clinics are located in three Space Coast communities – Rockledge, Palm Bay and Ft. Pierce. MIMA Pediatric Endocrinology continues to support the Florida Camp for Children and Youth with Diabetes through donations of medications, diabetes management supplies and weekly, annual volunteer physician services by Dr. Duncan. This camp provides endocrine physicians a superb opportunity to get to know their patients better while providing diabetes education in a safe, fun environment. Nearly 20% of the camp’s attendees come from the Space Coast area. Since education is a significant component of an endocrinologist’s role in the care of patients, Dr. Duncan provides educational lectures or group discussions for physicians, nurses, allied healthcare personnel, schools and parent groups. Many of his endocrine topics derive from the areas of research, which he continues as part of the practice.
