Y.S. Lee Martial Arts consists of a very close network of masters, instructors and students. The Y.S. Lee method of instructing and learning has always focused on the art of Tae Kwon Do (affiliated with WTF, or the World Taekwondo Federation). One key element that Y.S. Lee offers students is instruction from three WTF Masters at any given time, a benefit not offered at any other TKD school in the area.
