Balck Belts in 3 arts in 15 years may not be so difficult, in fact he may have gotten all 3 from the same instructor. Many TKD schools have a TKD and Hapkido curriculm. How good they are I cannot say. When I was at college (1975-1977), the school there had such a curriculm.
Then, the very same instructor may very well have a Korean / Okinawan roots. thereby allowing some sort of cross certification.
What you point out is noteworthy Stated degrees mean little. A close look at the reume is a better idea. But, in almost 20 years of running a school no one has asked to see mine, with th exception of those ITF people in thearea who may have already found it on the net.
Great to hear from you again and thanks for the response. My problem is not so much the black belt issue, as I know that it is possible. My problem is the term "expert" ! You better than anyone here knows the amount of schools I have had the privledge to visit. Not one of these owners have ever described themselves as "experts". TKDT's has of Mr Crawfis and Mr. Crawfis has it on his own website to describe himself, I always considered humilty as part of what a martial artist should personify. Again, he may be gifted an talented in technique, but I still have an issue of what this article is representing to beginners.
