Dude, Madys Karate. I was at Superkicks in Detroit cornering my buddy MMA fight this weekend and their guys cleaned up in their MMA fights. Their grappling trainer was a Canadian judo Olympic champion. (I live like a hour away and want to go down their just train leg kicks for a day.)
www.madyskarate.com I guess their grappling program is solid.
They got some studs man. I am sure the other places are descent too. But I can tell you first hand, these guys are the real deal. Good luck,
