Mr. Hadley began his martial arts training in September of 2000. He first began training in tae kwon do but quickly knew it wasn't the correct martial art when he began suffering from multiple joint injuries that wouldn't go away. He lost faith in his second TKD school when the school owner turned over the training to someone with less than a years experience in martial arts and began driving students away in droves.
While very successful in competition, scoring two bronze medals in the 2005 WCOAA Goodwill Games in Nuevo Vallarta Mexico, he realized he had no future in TKD.
William quickly switched over to the art of Choi Kwang Do after spending time at the Kennesaw headquarters and speaking to multiple school owners, instructors, and students. Since switching arts, he has suffered no injuries and has decided to open his own Choi Kwang Do school in the Milwaukee area. He hopes to open more schools in the future to spread the good word about CKD in areas that may not know what the art is about.
