17-1 ASSISTANT COACH
After not making the soccer team for a second year in a row, Callen decided to change
sports to volleyball as a sophomore at Harrison High School. Due to COVID-19 his year was cut short, but in the year following, he decided to make the shift to club volleyball at A5.
During his last two years of high school, Callen also began managing his high school's
women's volleyball team. This was the start of his career as a volleyball coach. After graduation, he continued to pursue his love for the game by managing his collegiate volleyball program at GCSU.
Following Callens freshman year, he transferred back to Kennesaw State, where he continues to stay involved by coaching volleyball at A5 with his old Coach.
