He has almost as many titles before his name as he has ranks.
Who you associate with says as much about you as anything else. The fact that he is associated with Humesky, and vice versa, speaks volumes about his credibility. The fact that Humesky would let himself be associated with such an obvious talent (major eye roll here) speaks volumes as well.
One of the organizations that Petrotta and Humesky claim membership in is the United States Martial Arts Association. I have been on the USMA website. There are more 10th dans who have founded their own styles than you can count. One that I found interesting is a style called Nel-Son-Ryu (I'm not making this up by the way), founded by a guy named Nelson. Of course he is 10th Dan in this style.
It goes back to what I said on another thread on having rank or certification, real or otherwise, in many different styles and organizations. One 10th Dan takes a lifetime to accomplish. How is two possible?
Anyway, I have met Humesky as well. Personally, I found him rather arrogant and full of himself. It could have been the weight of all those patches on his uniform
I have been on the UTB website as well. Humesky claims membership in close to 10 different organizations, and claims rank in WTF, ITF, Chang Moo Kwan, and at least one Chinese MA organization. Draw your own conclusions.
