John first met Allen in 1997 after he attended Allen's clinic in London and was cured of his 80-a-day addiction to cigarettes. So inspired was he by this experience that he determined to become involved in Allen's quest to cure the world of smoking. He was successful in this aim and describes the subsequent training he received from both Allen and Robin Hayley, now Chairman of Allen Carr's Easyway, as one of the best experiences of his life, and feels honoured and privileged to have counted Allen not only as his coach and a mentor, but also a friend.

John went on to personally treat more than 30,000 smokers at Allen's original London clinic, and led the team that have taken Allen's method around the world from Berlin to Bogota, from New Zealand to New York, from Sydney to Santiago. Drawing on the real-life experience of this global team of therapists, John worked closely with Allen and Robin to apply the method to alcohol, weight issues, fear of flying, gambling, debt, sugar addiction, caffeine addiction and a whole host of legal and illegal drugs. John is now the Worldwide CEO of Allen Carr's Easyway Organisation and one of the most experienced Allen Carr's Easyway Therapists in the world.
