I would like to add to this about his fake cerificates. Yes his certificates are 100% Fake. Also my son went to his school in Federal way and also tested for his FAKE black belt, When we moved I enrolled my son into a different Taekwondo school and they also said this certificate was a Fake and could not honor his rank,they told me that his certificate was only good at his schools and no other. I would just like to say to you Master Na you are full of it and I hope that more people come out. You sit around and have your Fake Black Belts teach your classes for you, and at the same time you go around and see how much more money you can get out of there parents, and you call your self honest and church going person I would hate to go to your church. Remember one thing WHAT GOES AROUND COMES AROUND.
