This means that his head instructors are 3rd generation and that Missouri Martial Arts students are learning authentic martial arts from the Kukkiwon.

Grandmaster Yoon is also important to our school because his teachings are the basis for the consistency of all the martial arts teachings at our school. Grandmaster Yoon has provided official and knowledgeable information to our school about tae kwon do, judo and hapkido.

Grandmaster Yoon’s Biography

A native of Korea, Grandmaster Chang Hee Yoon went to school in Seoul, Korea to get his college education and to train in tae kwon do, judo, hapkido, and other martial arts. Grandmaster Yoon trained in the traditional techniques and forms that are used today by the World Taekwondo Federation (WTF) Kukkiwon headquarters.

After college, Mr. Yoon served in the Korean National Army. While in the army, Mr. Yoon became Korea’s national judo champion and captain of the military judo team, his favorite martial sport. These are amazing accomplishments, as judo is as popular in Korea as NFL football is in the United States. The competition was extreme.

Mr. Yoon came to the United States in 1970 to teach martial arts. Mr. Yoon arrived in St Louis, Missouri, where his brother-in-law, Grandmaster Bong Yul Shin, resided. (Grandmaster Shin founded Gateway Moo Do Kwan schools in St. Louis in 1963.) Grandmaster Yoon soon thereafter founded Chang’s Martial Arts, which grew into five school locations throughout the St. Louis area, including Belleville, St Charles, Kirkwood, South County, and Arnold. As a result of his outstanding achievements, Grandmaster Yoon was invited to sit with the International Judo Federation (IJF) president at the 1988 Seoul Olympics.

Grandmaster Yoon has trained, mentored, and promoted hundreds of officially certified black belt students in traditional style martial arts over the course of the last forty years. This includes the head instructors of his three current schools- Bob Wheeler and John Moseley of Missouri Martial Arts, Dien Nguyen of Dien’s Martial Arts, and Tom Reid of World Martial Arts in Belleville, IL.

Grandmaster Yoon still resides in St. Louis. He has two sons, Jaeyoung and Jaemin, and a daughter Jackie. All three hold black belts in tae kwon do and judo.
