I was calling a round to find a new school. I live in Texas. The girl answering the phone said she was a 2 degree Black Belt. She asked If I had any experience. I said I had gone to one of Jack Hwang's schools. She said she had never heard of Jack Hwang. So then I ask had she heard of Jhoon Goo Rhee, she said no. I had no more questions. I do not know maybe I am crazy, but if you are a Black Belt living in Texas you should know who Jhoon Goo Rhee and Jack Hwang was. We can argue about the years need or what skill level a black belt should have, but Black Belts should know who Jhoon Goo Rhee was, who many consider the father of American Taekwondo.
