HAVOC was developed by Sifu Jay Cooper from his personal experience of confrontation while working for the Canadian police. As a recognised authority in Canadian and UK courts on ‘use of force’, he has expert knowledge in both the physical and legal aspects of combative situations.

Simon Sheridan

Sifu Simon Sheridan has almost 40 years of martial arts experience. It all began at the tender age of 17 when he began studying Kung Fu. This took him into his twenties, after which he added Jeet Kune Do and Eskrima to his skillset. In 2017 he was invited to be the first instructor to represent the UK arm of HAVOC Jeet Kune Do, and now teaches in Kent and at seminars around the country.

Simon’s continued research has exposed him to Muay Thai under Master Sken, Eskrima under Guru Khrishna Godhania (Warriors Eskrima), D.A.R.T (Karate) under Dr John Titchen, Tai Chi under David Arnold and Simon Watson and Simon has also been a private student of Grand Master Danny Guba (Doce Pares Eskrima).

Simon now teaches not only Jeet Kune Do, but also boxing, grappling and eskrima and offers one of the best self-protection programmes in the UK.

Andy Wheeler

Andy is a qualified apprentice instructor and is currently training under Simon in Kent. His martial arts experience includes Eskrima, Kung Fu, Shotokan Karate and Tang Soo Do. He is generous with his knowledge and has taught at seminar level to all ages around the county.

Andy has recently requalified as an apprentice instructor after a year long evaluation, followed by a mentally and physically demanding grading under the watchful eye of Sifu Jay Cooper and Sifu Simon Sheridan.

As an instructor alongside Sifu Simon, Andy teaches Jeet Kune Do, boxing, grappling and eskrima and also specialises in self-protection.

When he’s not in class, Andy enjoys riding his motorbike.
