Warrior Concepts was founded by Jeffrey M. Miller. Originally Miller's Martial Arts, the company was founded in 1989 to provide quality self-protection and personal development training to children and adults. The name was changed in 2004 to better reflect how we were different from the more conventional, sport and competition-oriented karate schools teaching mere punching and kicking skills. Shidoshi Miller is an 11th degree balck belt under Grandmaster Hatsumi-Sensei In Japan.
