Thousands of people in the UK, and many more globally, can legitimately claim to be Trainers of the subject matter – over 1,000 of those have been trained by David himself. However, since 1975, only a few have been given the title of Master Trainer. It is a title that is only bestowed to those who have demonstrated a phenomenal theoretical and practical understanding of the subject, not to mention complete over 2,000 hours of study, training and practice. David is the one of the longest standing trainers of such quality on the planet.
