Athletics - Concussion Protocols

Trinity High School takes seriously the physical, emotional and academic consequences of concussions. We strongly encourage students who may have sustained a concussion to see a physician who specializes in treatment of concussions and head trauma and we work with those physicians to help students fully recover so that they may not only return to play, but fully access their academic course of study.
