I am Domonique Knox and this is my second year coaching track and field . I began to run track in middle school as a mid-distance runner and transitioned into a hurdler. I continued to work hard and compete at the high school level where I became captain . Throughout my years of running, I also participated in AAU Junior Olympics . Once I graduated high school, I had an opportunity to continue my track and field career at Maryville University. The love I have for track and field is unmeasurable and it shows!
