Yes I too have heard from a few and read that there is a lot of controversy that follows this man. The opinios seem to be extreme that this Master Greg Alland is very good or that he isn't any good at all. That he is is a true highly developed Master of his art, and a champion, or that he doesn't know that much at all and that he scams everyone of money. I would like to hear more about the man from others and opinions too, because can both views be true? Is this teacher of martial arts divided in two, with two distinct personalities perhaps? I've never heard of so much differing views about one individual in the martial arts world.
