He is relatively unique in that he has been trained in gastroenterology, hepatology and nutrition, having successfully carried out his Medical Doctorate in energy expenditure in cystic fibrosis, and spent 10 years in liver transplant units with associated gastroenterological expertise, and subsequently made endoscopic assessment and treatment his main area of interest since being made a Consultant in 1994 in London. He spent 11 years at the highly acclaimed Centre of Paediatric Gastroenterology at the Royal Free Hospital in London helping to develop the unit there before moving to Sheffield Children’s Hospital.

He travels down to London 1-2 days per week in order to conduct paediatric gastroenterology clinics and endoscopy lists and has travelled widely around the world performing endoscopic procedures and clinics.
