Derrick Chan is a great martial artist, a fabulous teacher and an awesome guy to boot (no pun).

His Tae Kwon Do, Kung-Fu, Karate and weapon skills are hard to match in my view, and I have seen a fair bit around.

Never trained with the guy, so don't take this view point from a direct experience, but I have certainly witnessed his skill set and teaching method and would say he is probably one of the handiest guys in Perth to train with for self-defence.

If MMA and competition is your love, then he could help I am sure, but may not be the guy to train with in isolation??
