Over the next eight years, he practised dentistry on the Mediterranean island of Cyprus. During that time, he trained in homeopathy, abandoned the use of amalgam and expanded his knowledge of the biological aspects of dental therapy. In 1998, he moved to Los Angeles and received his licence to practise in California in the US. He owns a state-of-the-art biological dental practice in Glendale in California.
