About Jason Boh

I began my journey in 1983 when I was 9 years old, under Sensei Mervin O'Donnell. I began learning Shotokan Karate and gained my Shodan (1st Dan) black belt when I was 13. I then became very active in assisting my Sensei in teaching classes and continued to work through the grading system for my own development. I competed regularly and represented The South Of England Karate Union (now Shotokan Of England) at national level.

Whilst attending a Geoff Thompson seminar I was very fortunate to train under Rick Young who indirectly introduced me to Jeet Kune Do (JKD). Not knowing how world widely renowned Rick is for his abilities as an instructor and martial artist, I was in awe of this fantastic individual and came away totally inspired. I immediately looked for a decent JKD school local to me and remembered a man named Bob Breen who taught JKD in London.

One phone call later, I found myself on a JKD/Kali International Instructor Camp for a weekend's worth of training under one of the best JKD Instructors in Europe and a full instructor under Guru Dan Inosanto (Bruce Lee's friend and training partner). I have been studying with Guru Bob Breen for a number of years now and am currently apprentice level 2 under his JKD/ Kali International programme. I make regular trips to his academy in London where I enjoy training under Guru and alongside other top quality martial artists from across Europe.

During another JKD seminar, I was fortunate to be introduced to a man called Terry Barnett. Terry is also a full instructor under Guru Dan Inosanto and teaches from his home in Hertfordshire. I have been a private student of Terry's for some time now and I honestly feel that I have progressed rapidly due to his ability to be able to break things down and pass on knowledge which is easy to understand.

The Martial Arts is a life long journey of self expression, not just a means of self defence, although this is certainly an excellent added benefit. Martial Artists of all levels are constantly learning and growing, nothing remains still for any length of time. This very much inspires me to continue to aim for the highest level and to try and be the very best I can be, as a person as well as a Martial Artist.

I was very honoured to be asked to train the Royal Navy Karate Team in preparation for their annual tournament, which I accepted and enjoyed doing so for a number of years.

As well as teaching regular classes, I currently teach private lessons and I am also asked to provide workshops and seminars for various groups such as youth club organisations and schools. I am very proud to have such dedicated and fantastic students and also instructors who assist me in running the school. We all socialise outside of class on a regular basis and enjoy evenings to the cinema, pubs and restaurants - even if the conversation always returns to Martial Arts!!

I have genuinely loved every minute of my Martial Arts journey and I hope to continue for as long as I possibly can. I hope you will climb aboard and share this life long journey with me.
