Grandmaster Soo Woong Lee is a 9th Degree Grandmaster and was one of the first Taekwondo Masters to come to the United States in the late sixties, and Martial Arts USA was one of three schools in the Bay Area that he owned. Grandmaster S.W. Lee’s students became some of the most talked about competitors during the seventies, and during the eighties he moved to the West Coast to open a series of taekwondo schools that placed a direct emphasis on developing a program to help change kids’ lives. Along with his son Will Yun Lee, he developed a kids karate success program that is described as helping tens of thousands of kids do remarkably better at school, home, and in social settings, and Martial Arts USA offers a mini-documentary on its website in the ABOUT section on Grandmaster Lee and Will Yun Lee. Will Yun Lee developed the children’s programs in the eighties and nineties and later moved to Los Angeles to pursue an acting career, appearing in many films and TV shows.

Parent testimonials describe the instructors as friendly, knowledgeable, patient, kind, and dedicated, and several families mention feeling like the studio is a “second home” or “second family.” Families such as the Suarez, Libarle, Kimble, Giosso, Thirion, Arnoux, Santamarina, Sheehy, Hall, and Dixon families describe experiences that include kids enjoying Tae Kwon Do, sticking with the activity over multiple years, and participating in small enough classes for individual feedback. One family notes that their child completed a 2nd degree Black Belt and Instructor qualification after almost seven years at Martial Arts USA, and another mentions birthday parties at the studio, including one described as the “best Birthday Party ever.”
