PERTH — An Amsterdam orthopedic surgeon is so upset about the number of Tryon Residential Center staff members he treats that he plans to write to state officials, he said. Dr. Gerald J. Ortiz, a board-certified orthopedic surgeon with Mohawk Valley Orthopedics PC on Route 30, said Wednesday there is a problem with what is going on at Tryon because he’s continually treating staff from the facility. Several youth division aides, both on the boys and girls sides of the state Office of Children & Family Services’ facility, have said aides are being assaulted more than ever at Tryon. “It’s getting ridiculous,” Ortiz said. “I feel I should do something. Every week, I treat at least two guys [Tryon employees] who have been assaulted. They’ve either been assaulted or hurt restraining a kid that’s unruly.” Ortiz said he’s never seen such an increase in his patients from Tryon, which have included both male and female staffers.
