With so many martial arts schools in operation today, it is not easy to decide where to begin your own training. However the choice is easier than you think. Master Jang and his staff take great pride in the uniqueness and excellence that is JSK! Our schools are affiliated with World Taekwondo Federation (WTF), Usa Taekwondo(USAT), Kukkiwon(World Taekwondo HQ). There are 14 branches of JSK taekwondo in the world. 4 schools in Korea, 8 schools in China and 2 school in United State. JSK is the ultimate place to dedicate yourself to attaining your personal goals and accomplishments… Perhaps a Black Belt…
