Anyone here know Jason Landaas? He has a school in N. Carolina and is supposedly the Head Instructor for Chun Moo Hapkido in the U.S. but his school looks to be struggling and his attitude is very arrogant.
Na, never heard of him.
You say that his attitude is very arrogant, are you sure that's him in general or just at that particular moment in time?
If you're implying that he is a questionable Martial Artist, then this isn't the place for it - see this part of the forum for that - http://www.bullshido.net/forums/forumdisplay.php?f=10
