As said, Hargrave is currently teaching both American Combat Kempo and Jeet Kune Do in his private school, Hargrave Martial Arts. Before opening this school he also had several other schools but he wasn’t satisfied on how they were operated. He wanted to open a private one in order to be able to select those who join and to make sure that the arts he is teaching are only used in defense purposes.
Carter Hargrave also uses his teaching abilities in order to do community a good and he provides free training to medical missionaries that have to provide medical service in areas where their safety is at risk. See Carter Hargrave Wiki for more information.
