In August 1985 John set-up Portland Ceramics, covering crown and bridge, prosthetics and implantology. After the acquisition of Portland Ceramics by Boots Dental Care, John delivered lectures nationally and internationally. John continues to lecture regularly on the topic of implant-retained dentures and denture stabilisation. He has delivered lectures in Japan, Las Vegas, Spain and Brazil.
In recognition of his hard work and positive influences in the industry, John was awarded with the title of Fellow of the British Institute of Dental and Surgical Technologists in June 2005. He also served some time on the board of The Dental Laboratory Association, as Director of Education where his enthusiasm and energy made a significant impact.
After recent extensive training in Japan with Professor Jiro Abe, John became an international instructor in the Lower Suction Denture Technique, one of only a few clinicians worldwide.
