Dr. Barrett Peterson, 58, passed onward July 4, 2018, surrounded by family and friends, after a three-and-a-half-year battle with a rare cancer, Pseudomyxoma Peritonei (PMP). Barrett completed dental school and an orthodontic residency at Tufts School of Dental Medicine. Upon graduating, Barrett joined Champlain Orthodontics in Vermont, forging bonds with his partners, staff, patients young and old, and his fellow dentists. He was enormously proud of his participation in the Vermont Cleft Palate-Craniofacial Clinic. Barrett's life was marked by exuberance, professionally and personally. He will be missed by all who knew him.
