(Thru martial arts) Everything is possible, if you want it bad enough. And are willing to work for it.
— Grand Master Chung

Grand Master Chung earned his 10th degree Black Belt from the World Martial Arts Federation in Tae Kwon Do, Judo, and Kyuki Do.  He is one of the few to hold these prestigious ranks in 3 separate styles.  He is also one of the youngest to reach these ranks.

Through dedication and discipline, which he developed early in life, he has accomplished all the goals he has set for himself. Due to his modesty, the honors, awards, and numerous citations he has received, Master Chung has created a following of students who seek to model their lives after his example.

Students who have trained under him have learned more than how to punch and kick. They have received training by his good example in self-control, patience, discipline, and confidence.
