Grandmaster Richard Chun began studying Taekwondo at the age of 11 under two highly repected teachers in Seoul, Korea: Chon Soo Hong and Ki Whang Kim. He progressed to 9th Dan by Kukkiwon in 1989 (World Taekwondo Federation) and Moo Duk Kwan in 1981 after more than fifty years of study, establishing him as one of the highest ranking master instructors in the United States.
