The pupil has become the teacher.After four years of playing for the Lady Pioneers and spending one season as an assistant coach, Katie Wanamaker was named the new Warren County High School volleyball coach in March. Wanamaker, 22, is the third coach for the program in the last three years as she takes over following Dena Upton’s two-year tenure.Wanamaker takes the reins just four short years after leaving the program as a four-time, all-district performer when she graduated in 2011. Being new to the job at a young age has left Wanamaker with some nerves to go along with the thrill of a new opportunity.
