wow I didn't expect master Van Lenten's name to pop up here. He's done a lot for the art, but i've seen on other forums and such that there is some controversy surrounding his organization. That being said, I couldnt care less, I've met Master Van Lenten several times and my Shihan was and is one of his students. He's older now, but every time he's visited our dojo he's been really helpful to all the students. He loves goju and karate without a doubt. I think he's a great guy and I owe him a huge debt.
