BANGOR, Maine — Brad Libby is a successful area businessman. The licensed physical therapist owns Performance Physical Therapy and Sports Rehabilitation locations in Bangor and Brewer. Last winter, to make sure his business was running smoothly, he stepped away from basketball and his role as an assistant coach under Warren Caruso at his alma mater, Husson University. That time away convinced Libby that he needed basketball in his life. Libby will be back in the game next season after he was approved as the boys varsity basketball coach at Bangor High School during Wednesday night’s Bangor School Committee. “I’ve always been working towards that head coaching level and I’m super excited for this opportunity to go to Bangor and continuing their tradition of basketball and the success that they’ve had,” Libby said. “He’s going to be terrific,” said Bangor High School Principal Paul Butler. “(Athletic director) Steve (Vanidestine) and I are really optimistic, have a lot of confidence in Brad.
