Professor Rick Clark is a specialist in applying pressure points using techniques from the katas/patterns. He has a very good understanding of both Japanese/Okinawan katas as well as Korean. When you see his qualifications, you’ll understand why:
8th Dan Ryukyu Kempo
7th Dan Tae Kwon Do Chung Do Kwan
7th Dan Ju-jitsu

As well as having one of his books, I’ve had the pleasure to attend one of his courses when he came over to the UK. He’s a very easy going gentleman who is very approachable and extremely knowledgeable.
