9th Dan Taekwondo

With well over forty years of experience as an instructor, Grand Master Ko has made it his life goal to combine Eastern and Western styles of exercise to create the safest and most effective form of exercise for everyone, no matter what age or fitness level.

He is a 9th degree black belt under Kukkiwon, the World Taekwondo Federation, with deep knowledge of Taekwondo, as well as Hapkido and Tai Chi. He is also a Certified Personal Trainer, MMA Conditioning Specialist, Corrective Exercise Specialist, and Performance and Enhancement Specialist through the National Academy of Sports Medicine and holds a Master’s Degree in Exercise Science, allowing him to utilize modern scientific findings to enhance our martial arts training.

Grand Master Ko’s contributions to the world of Taekwondo have led to international recognition: He has served as the US National team manager and coach for the World Taekwondo Championships in 1991 (Athens, Greece) and 1995 (Osaka, Japan) and President George Bush commended him for contributions as Tournament Director of the 18th US National Taekwondo Championships for the Selection of the US National Olympic Taekwondo Team at the Hampton Coliseum in 1992. He is a former President of the VA State Taekwondo Association. Before coming to America, he was an instructor for the Republic of Korea (ROK) army and Captain Instructor of the Chun-buk National University Taekwondo Championship Team.


5th Dan Taekwondo

Taekwondo has always been a part of Master Sang Mee’s life, seeing as her father is Grand Master Ko. However, she originally majored in Environmental Science at the University of Virginia before realizing her life’s ambition was to strengthen people’s minds, bodies, and spirits through martial arts and strives to be a positive role model for all her students.

Master Sang Mee is a fifth degree black belt under World Taekwondo and has over 10 years of experience teaching all ages. In college, she was President and head instructor at the UVA Taekwondo Club and helped create the Atlantic Collegiate Alliance of Taekwondo (ACAT) to encourage friendly competition between southeastern Taekwondo clubs.

Before coming to our school, Master Bozarth owned and taught karate at Morning Martial Arts (1989-1991) with a 1st Gup in Goju-Ryu Karate. He now also has a 5th degree black belt in Taekwondo and been with WMA for over 17 years as an instructor and occasional carpenter – many of the wooden apparatus around our dojang were custom-made by him, such as the window bars, weapons rack, benches, and more!

Master Bozarth is also a certified USA Taekwondo (USAT) referee and often volunteers at local competitions to bring the spirit of Taekwondo sportsmanship to life. He is retired from the United States Air Force with a Bachelor’s in Business Administration.
