Grandmaster Sun Ki Chong


Master Chong’s World Class Taekwondo Centers were founded by Grand Master Sun Ki Chong. Grand Master Chong is one of the leading Taekwondo instructors in the world. He is both a former Korean champion, as well as a former head coach for the U.S. National Taekwondo team.

He personally developed the curriculum taught in our centers and designed it to be a balance of traditional Taekwondo forms, practical self defense, and Olympic Style sparring skills.

Grand Master Chong’s philosophy is that Taekwondo is about self improvement as well as self defense. This is evident in our teaching methods. Our instructors focus on teaching “life skills” just as much as physical techniques. We help students of all levels to gain increased focus, confidence, and determination that they can apply to all areas of their life.
