THIS, is much more important than asking "well who the **** gave them a black belt!?"
No. A couple of years ago when I was a blue belt and I heard they were there, I called and asked if I could stop in and train with them. I told them I was a Blue Belt at the time and I had some MMA experience. They told me not to bother coming in and they are not interested in having me train with them.
My problem with the whole thing is that I don't believe they are qualified to teach MMA. I don't think they even really know what MMA is.
When you claim to be a black belt in MMA but have no MMA experience, that is, well, fraudulent to a degree.
I think they have a decent program when it comes to karate, family, kids and that but the whole MMA thing is definitely questionable.
