About Jackson Pediatrics

Serving our community since 1972

Jackson Pediatrics is the oldest and largest pediatric medical practice in Teton County. Our board-certified pediatric physician specialists work with infants, children, and adolescents through all phases of development. We are devoted to the comprehensive care of children in sickness and in health.

Jackson Pediatrics is the only facility in the region where your child will always be seen by a board-certified pediatrician, five days per week. Our physicians are all on the medical staff of St. John's Health, where we provide neonatal, pediatric, and intensive inpatient care.
