Dr. Junehee Kwon

Ms. Junehee Kwon, 4th Dan Black belt.

Junehee is a professor in the Department of Hospitality Management at Kansas State University. She started her Taekwondo training in 2008, shortly after her children started Taekwondo classes at Sun Yi’s Academy. She currently holds the 4th-degree black belt, Junior Master rank and is an internationally certified Taekwondo instructor.

Working out with her children has been fun and rewarding for over a decade now. All of her children achieved a black belt (Kyle 3rd, Faith 4th, and Grace 2nd degree), and the family-friendly environment at Sun Yi’s has motivated her to continue training in Taekwondo. Now, she is more physically fit and stronger than before, and she feels confident in defending herself. She loves teaching Taekwondo techniques to children and adults and plans to continue training even after her children leave home.
