Master Ko Se-hwan (고세환, 6th dan) is master Ko Baek-yong’s second son. Master Ko Se-hwan practically grew up with martial arts and learned his first steps in his father’s gym. After he served in the army, master Ko Se-hwan started training with his father even more regularly. In the following years he accompanied his father on overseas trip and in later years started teaching internationally on his own as well.

Although his father’s teachings obviously had the biggest influence on master Ko Se-hwan, there were and are other people that had a big influence on his style. Most notably these are master Han Si-hwan (hankumdo) and master Seo Myeong-won (taichi).
