He was then invited by the Head of Orthodontics at Birmingham Dental Hospital to become a Clinical Tutor of Orthodontics for the undergraduate programme. His fifteen-year career at the hospital gave John the opportunity to ask some of the best students to join his team on their graduation.

In 2002, following further study and assessment, John was awarded Specialist Status in Orthodontics by the General Dental Council and his name was placed on the Specialist List.

John now devotes himself fully to Specialist Orthodontic Practice and is proud to be continuing the development of his practices so that they remain amongst the best Orthodontic Centres in the country.
