He is currently studying part time at the University of Edinburgh for a Masters in Restorative Dentistry and he hopes that all of his patients will benefit from the extra skills that he is developing over this three-year course.


John has a keen interest in all forms of oral surgery and root canal treatment, however, his main focus is to maintain the high standards of patient care at Platt & Common and ensuring that the practice continues to grow and develop.
