Let me speak to the claim that this guy is a World Champion. I recently moved to Ashburn and began looking for a studio to enroll along with my son. I stumbled upon this tiny place while eating at a neighboring restaurant and was very hesitant to believe that a real WORLD CHAMPION was teaching in Ashburn (as I have trained for over 20 years and never heard of him). I decided to stop in and politely inquire with the owner about his rather shady credentials and, in disbelief, I watched as he grew increasingly angry and frustrated over the most basic of questions. He did not know the name of his opponent in the ""final match"" nor any information regarding the nationalities/style/ranks/weight classes of the other participants, the name of the sponsoring organization, or even when and where the supposed tournament took place. If this place is going to claim to teach honor, integrity, TRUTH, and discipline then they must display those same principles. All I asked for was some concrete evidence (other than a poorly edited 10 second video clip) that such an enormous achievement was legitimate. Be careful and do your research folks (there's no documentation online or anywhere about either the father or the son's ""competitions."" I guess these days anyone can buy a belt and call themself a World Champion.
