Justin qualified as a dentist from the University of Wales College of Medicine in 1989. Following hospital posts and a position as registrar in restorative dentistry, Justin gained his Fellowship in Dental Surgery and was accepted on the postgraduate orthodontic masters course in Cardiff in 1993.
After qualifying in 1996, by now having dedicated five years of postgraduate education to becoming a specialist orthodontist — one of just 900 or so in the UK — Justin took up a specialist orthodontic senior registrar post in Sydney, Australia.
He became acting head of department and published articles in the American and British Journals of Orthodontics and, following a two-year period as an associate dentist in Bristol, Justin returned to Wales and joined the North Cardiff Orthodontic Centre.
He later co-founded Embrace and Crocodile, a children’s private orthodontic clinic, with his business partner and fellow specialist orthodontist Martin Rees.
In his spare time, and when time allows, Justin spends time on his family run small holding.
