My son has been a student at Club TKD for 1 1/2 years. His teachers and even the Principal at his school have all commented on his greater maturity and self-confidence. As a parent, I appreciate Master Yoo's commitment to developing the character of his students, both in and outside of the studio. I have nothing but praise and the highest repect for Master Yoo, Instructor Julie, and the other instructors and students at Club TKD.
