For the past 12 years, Dianna Sager has been a big part of Colleyville Heritage High School, on and off the basketball court.Sager, in her 24th year in education, has been a physical education and health teacher and the head coach for the girls basketball team for the Lady Panthers, but she began another role for the first time when she became Colleyville's athletic coordinator in May. “They were looking for someone who was at the school all the time, and I have my masters in administration and principal certification so I knew I could do it,” Sager said. “I knew the job requirements and didn't mind taking on the role.”On the court, the Lady Panthers have made nine trips to the state tournament, the last coming in 2013. She coached the team to a school-record 29 wins in 2007 while qualifying for the regional tournament for the first time in school history. Being a successful coach is something Sager thrives on, but she believes that by the athletic coordinator role won't take anything away from coaching.“A lot of schools here do that, where one of their coaches will be athletic coordinator, and since I know the requirements, I didn't think it would affect my coaching,” Sager said. The only thing the position will take away is her ability to teach and manage two sports, something she has been doing for the past six years.Sager has been teaching physical education and health classes three or four times per day for quite some time, and for the last six years, she has also been coaching the cross-country team, in addition to every thing else. Starting next academic year, she won't be teaching in the classroom for the first time since her arrival at CHHS. “I guess the only thing it takes away is my ability to teach and coach two sports, so I won't be as busy,” Sager said. “One day, I hope to go back to the classroom and teach because I love interacting with the kids.”Some responsibilities that Sager will have to deal with as athletic coordinator are coming up with schedules, making sure each team and staff has everything it needs, making sure the gym is ready for all games and having the right athletic period for each sport, every season. The Lady Panthers finished last season 25-11 and were District 5-6A champions. In 2007, the Lady Panthers were bi-district, area and quarterfinal champions. Under Sager, the team has been district champs four times. Starting this fall, Colleyville Heritage will be moving to Class 6A and playing such powerhouses as Southlake Carroll and Coppell, but Sager believes the movement isn't as important as the team just going out and competing game in and game out. “It's not as important to us. We're a fairly newer school, so we just want to go out and compete with the other schools in the same district,” Sager said. Sager will strictly be in charge of girls athletics, while Darren Allman, the Panthers head football coach, will be the boys athletic coordinator.
