Traditional Japanese Karate

Karate/martial art is an outstanding way for kids and adults to improve physically and mentally. As students advance from white through black belt, they gain advantages of strength, flexibility and endurance, as well as improved concentration, discipline and character. The All American Black Belt Academy, located in Dublin/San Ramon, California, is family oriented and offers instruction in the Shito Ryu style of Japanese karate. The All American Black Belt Academy has several locations in Northern California.
