This is a very difficult question to answer. First of all I study & teach Kempo or as I have been told since my first day training in Kempo ... (Shaolin Kempo) I'm not going to say which Kempo group I study under or teach for as that will just open the flood gates to another moronic debate about he said, she said & your this & he's that! Besides in the big picture it doesn't really matter anyways.
Kempo/Kenpo or whatever's history shoots out into so many different directions it's really hard to say who brought it here & there who started this or that because there are so many groups, schools, teachers, students & strong personalities within the Kempo/Kenpo family & I stay clear of the politics of Kempo/Kenpo or whatever as if I wanted to become involved in politics I would be spending your hard earned tax dollars right now with the rest of the political leaders ...(Crooks!) in Washington DC but! ... Back to Kempo/Kenpo. Students of mine come to me & ask me lots of questions about this group & that group or they have heard this & that & I refuse to talk bad about other Kempo/Kenpo groups because I know many people that are involved with these other groups', teachers' etc ... In the end what's really important is the Kempo. It's a great art & if you train, study or teach Kempo/Kenpo then more power to you!
