Peter Johnston

Practice Owner

GDC Reg: 67704

Peter Johnston is our principal dentist and owner here at Castleton. Having taken over the partnership in 1998, there is no denying Peter has experience on his side.
Peter qualified in 1992 and went on to complete further qualifications (DPDS) in Restorative dentistry and Endodontics in 2000. Peter has a special interest in and is passionate about Endodontics enabling a perfectionism to take form through thorough and intricate root canal fillings. In recent years, Peter has taken over sole ownership of the practice as we saw his colleague, Ulla Morrison, retire after 30 years at the practice. Peter’s sheer talent, hand in hand with his professionalism and knowledge of the industry, contribute to his long established and adoring patient base. Despite 2017 marking Peter’s 20th year at Castleton Dental, word of mouth around Farnham still serves Castleton well, reflected by our ever-growing list of patients.

Peter is an avid sportsman, with interest in playing squash and golf. He enjoys skiing with his family and is always paying close attention to what’s happening at Wimbledon. Peter is married with 3 children and loves spending quality time with them– even though he feels his children are growing up too fast!
