Master Yoon G. Chang brings the precision and artistry of a world-class competitor to every class at Regulus Taekwondo. A 6th Dan Black Belt certified by the Kukkiwon and a graduate of Kyung Hee University in South Korea — where she majored in Taekwondo and Physical Education — Master Yoon represents the gold standard of formal Taekwondo education.
Her credentials extend across both Korean and American Taekwondo institutions.

Master Yoon's accolades reflect her national and international stature. She is a recipient of the Presidential Active Lifestyle Award (President of the USA, 2009), a Certificate of Recognition from the World Taekwondo Federation (2010), and the Commissioner's Award from USA Taekwondo MAC (2019). Her demo team performances have been recognized by the City of Los Angeles, IL State Championships, the IL Demo Team Festival, and the Michigan USTC.
Master Yoon has served as Head Master at Elite Fitness Taekwondo in Irvine, Director at American Martial Arts Academy in Naperville, IL, and Assistant Master at Sunrise Martial Arts in Corona Del Mar — building one of Southern California's most respected demonstration team programs along the way.
