Fuller explains that his schools have a unique approach to martial arts that centers on helping kids grow.

"Our emphasis is on personal development," he said. "It's not on the art of karate itself - that's where we're different. Most other instructors just teach the art. We teach the person first, and the art comes later on."

Fuller rewards children for positive behavior and good grades. U.M.A.S. Karate has several classes for children aged 3 to 12 and classes for older teens and adults.
