EXCELLENT Based on 11 reviews Kevin2024-06-19Trustindex verifies that the original source of the review is Google. I have been training with JP Sensei for 5 years now, since I moved to the Peninsula. JP Sensei offers an enriching experience in all aspects of karate do. You may be interested in karate for its physical fitness benefits, the philosophy, or technical details. You may be looking for structure and discipline or a physical outlet from your daily routine. Or you may be interested specifically in sport kumite, kata, or the self defense applications of karate do. Whatever your interest, JP Sensei has the expertise, experience, and teaching prowess to instruct in all of these arenas. You will get out of karate what you put into it, and JP Sensei is a world class instructor who will help you achieve whatever your karate goal may be. If that's not enough, the dojo is also a very welcoming place. The dojo members are a great group of people who are enthusiastic about karate.

Sensei JP Williams poses in-depth knowledge about karate which he has been practising for decades. He trained with the best of the best. He is the author of an amazing book about history of goju-ryu, where he did extensive research about the style. Sensei teaches not only the technique of karate, but also helps you understand the philosophy behind it. I could not be happier with our group.

The class is always interesting. Arthur Turner2018-04-28Trustindex verifies that the original source of the review is Google. I’m a professional Educator and Goju practitioner from Dallas Tx. Ive been training with Johnpaul Williams since the death of my original sensei in 2014. Training with Sensei Williams has been a absolute blessing! He’s a excellent teacher. He has made every effort to train me regardless the distance (Dallas to Cali). He’s very traditional and well cultured. I like how technical, and how easy he can simplify kihons, Kata and kumite. I can truly say I’ve been learning a lot from him. Anyone training with Johnpaul Williams will benifit from him. If you want to learn good karate, then you found the right Dojo.
