History
Martial Arts USA Est. 1993
One of the first Taekwondo Masters to come to the United States in the late sixties, Grandmaster Soo Woong Lee opened up his first school on the east coast. His leadership, along with a few others, helped sparked the popularity of the art in America. Grandmaster S.W. Lee’s students became one of the most talked about competitors during the seventies. During the Eighties, he moved to the West Coast to open up a series of taekwondo schools which placed a direct emphasis on developing a program to help change kids lives. Along with his son Will Yun Lee they developed this kids karate success program that helped and continues to help tens of thousands of kids to do remarkably better at school, home, and social settings. You can watch a mini-documentary on our website, in our ABOUT section, on Grandmaster Lee and Will Yun Lee!
Martial Arts USA was one of three schools in the bay area owned by Grandmaster Lee. One of his prize students was a young boy who walked into his Napa Studio in 1988, Mr. Scott Sinan. Since becoming a black belt, Mr. Sinan has taught and helped at all of his schools. When the opportunity came to own and run one of the studios, Mr. Sinan jumped at the chance. This young man would pave the way for another generation of young champions to become successful at home and school through the martial arts.
Will Yun Lee since developing the children’s programs in the eighties and nineties, moved to Los Angeles to pursue his acting career. He’s appeared in many films and TV shows over the years.
