He has had a number of Celebrities as students as well as stuntmen.

An eternal student, David started his martial arts training in 1979 being taught Hapkido and kickboxing by his older brother.

In 1983 he started Wing Chun (whilst still practicing Kickboxing) and practised that style continuously into the early 2000s.

He took up the study of Bruce Lee’s Jeet Kune Do and Filipino martial arts at the World famous Bob Breen Academy in Hoxton in 1996, later becoming the first FULL INSTRUCTOR under Guro Bob Breen in 2008 as well as an Instructor under Guro Terry Barnett of Integrated arts in 1998. In  1998, He was accepted on to the Instructorship program of Guro/Sifu Dan Inosanto who was of course Bruce Lee’s top student.

Following the principles of JKD, ‘absorbing what is useful’, David went on to study and become qualified in the system of MAPHILINDO SILAT created by Guro Dan Inosanto and was awarded the title of ‘Guro’ in 2005 becoming only one of a handful at that time.

Responding to the need to further his knowledge and skills, David trained Combat Submission Wrestling (CSW/MMA) with 2 X World light Heavyweight shooto champion, Sensei Erik Paulson, and after completing the earlier coach levels, he was awarded the level of ‘Representative Instructor ‘ in 2004.
