About Kelly Worley

Mr. Worley began his karate career in 1977 and received his first degree black belt in 1991. Shortly thereafter, he earned the title of #1 overall forms and sparring competitor in the NCKA for two consecutive years. Over the course of his teaching life, one of his many joys is seeing his students from the past bring their children to receive the same training they received from him as children.
