Where is Craig?

Hi everyone, I'm looking for a brazilian jiu jitsu school in Philadelphia in which Craig Kukuk and I believe Renzo gracie are the instructors. I called a telephone number I got off the web but it was either disconnected or completely wrong.
Would anyone happen to know if the school is still around? Or better yet the whereabouts of Craig or Renzo, I've heard many good things about their skills and I would like to meet them.
Thanks in advance for the help.

Was this the number that you called? (800) 458-5878

Thanks for your prompt response. The number I called was a 908-somthing number. It may have been their old school.
I actually just found where Craig is , that's a club in Boise Idaho.
