I am dual qualified as a General Medical Physician and Gastroenterologist. I have worked as a Consultant at the Luton and a Dunstable NHS FT University Hospital for over 10 years and provide private specialist gastroenterology support and advice for the people of Hertfordshire and Bedfordshire through Spire Harpenden Hospital. I cover a range of general gastroenterological issues such as constipation, diarrhoea, bloating, abdominal pain, irritable bowel syndrome, food allergies and intolerances, acid reflux and indigestion (dyspepsia).

I have been the Clinical Lead for Gastroenterology at the L&D and at Spire Harpenden. I am a core member of both our local upper gastrointestinal and colorectal cancer multidisciplinary teams. Unlike general Gastroenterologists I also perform capsule enteroscopy and oesophageal manometry studies. I am fully competent in a range of diagnostic and therapeutic endoscopic procedures having completed >3,500 Upper Endoscopies (OGDs) and >3,000 colonoscopies, with one of the highest caecal completion rates of 98.5% in the UK, with good comfort scores (results published openly on the National Endoscopy Database).

I am the Lead Consultant in gastroenterology at the Luton and Dunstable Hospital, Bedfordshire. I am also committed to teaching and research. My private practice mirrors that of my NHS service, where I aim to provide high quality care with an open and friendly approach.

I offer my services at the Spire Harpenden Hospital in Hertfordshire as a General Medical Physician, Gastroenterologist and Endoscopist. I cover general gastroenterological issues such as Irritable Bowel Syndrome (IBS), functional bowel disorders, food allergies and intolerances (eg Coeliac disease), acid reflux and indigestion (dyspepsia). Within my NHS practice I also run the oesophageal cancer stenting and am a core member of the colorectal cancer screening and MDT. My practice mirrors that of my NHS service, where I aim to provide high quality care with an open and friendly approach.

I graduated from St George’s Medical School, London in 1995. I underwent postgraduate medical training in the South East Thames region and am now dual accredited to practice general medicine and gastroenterology. I completed a Research Fellowship at St Mark’s and St Thomas’ which led to a Master’s degree in 2009 and several publications assessing the effects of bacteria and probiotics in inflammatory bowel disease (IBD). I trained through Guy’s, Kings and St Thomas’ Hospital rotations, completing my MD research at St Mark’s.

I have research interests in Coeliac disease, Inflammatory Bowel Disease, Capsule Endoscopy, oesophageal dysmotility (eg spasm), and non-invasive bowel investigations.

Outside of medicine most of my time is dedicated to my family. I also enjoy singing, playing the guitar and writing music. On more energetic days you might catch me cycling around the Chiltern hills. I live locally to the hospital and have just acquired an allotment, so spend a lot of time pulling weeds!
