After completing his National Service, John developed a career in senior management and at board level with international companies. When in his fifties he decided to quit big business and re-train as a fine artist. He studied with The Open College Of The Arts, where he gained a distinction in his final year, and supplemented this with further studies at The Slade School, Central St. Martin's College and the John Soanes Museum. These added studies covered life drawing and painting, portraiture and developing water colour technique.

In 1998 John had his first exhibit in the Not The Royal Academy salon de refusee, run by Llewelyn Alexander in London. It sold on the first day of being shown. The following year saw his first one man show at The Oxo Tower Gallery in London which has been followed by a number of one man shows in London and also in Kent, Richmond and Corsica. He has also shown in many mixed shows, including one in the House of Lords. His work is represented in many private collections in the UK as well as France, Cyprus, Corsica, Italy, Singapore, Switzerland and the United States of America.
