I enjoy all aspects of gastroenterology and hepatology but have special interests in endoscopy, bowel cancer screening, pancreatic and biliary disorders and viral hepatitis.

I provide an outpatient practice covering all aspects of gastroenterology and hepatology at Spire Harpenden Hospital. I also perform diagnostic and therapeutic endoscopy and colonoscopy on-site at Spire.

I graduated from The Royal Free Hospital School of Medicine in 1991. I completed my specialist training in gastroenterology and general medicine on the South East Thames Specialist Registrar training rotation which included posts at King's College Hospital Liver Unit and Guy's and St Thomas' Hospitals. I undertook research at St Thomas' Hospital, which led to a PhD from the University of London.

My NHS links allow me to offer comprehensive and rapid investigation and treatment of patients with gastrointestinal complaints.

I live in St Albans with my wife and two young children. I am a skiing fanatic and year round I do slalom racing, competing on a national level. In the winter I enjoy ski touring and freeride skiing. I also enjoy music, and play piano and guitar.
