He passed away 8 years ago. he started a branch of his own version of American Kenpo here in New England. from what I've seen, they are centered around participating in local tournaments, although that was the 80's and I haven't seen what they've been doing since. I've watched their local demonstrations before (again, in the 80's), they were superficial and mcdojo-ish.
I guess it could be good now, or perhaps I only saw the only 2 bad schools it has....but I never paid attention to it after seeing it demonstrated.
