As part of the KI family, we are proud to offer specialized training, exercise, fun and life skills training to students age 3 to 100! Offering one of the few sports your family can do together, at KI Lewisville we're a family dojo (school). Parents train with their children and family events are a regular part of our schedule. We're especially proud of the life skills lessons that we inject into every class. Our mission is: To better the lives of our students via committed leadership, empowering them to make better life decisions and defend themselves if necessary. A LEGACY OF BUILDING LEADERS. Karate International has been in existence since 1957 and has served NC since 1974. We've trained many hundreds of students to black belt and played a large part in their success outside the dojo. With requirements that go beyond the physical into good grades, discipline and leadership, we've been building leaders for over 50 years.
