With over two decades of experience, I am a distinguished Consultant Gastroenterologist and a leader in advanced endoscopic procedures and nutritional care. I am known for my compassionate, patient-centered approach and commitment to improving outcomes for those with complex gastrointestinal and liver conditions.
I specialise in advanced endoscopy and managing various chronic gastrointestinal conditions. Endoscopic procedures which I have been highly rated for include endoscopy (gastroscopy), colonoscopy, endoscopic ultrasound and ERCP procedures. I perform various complex advanced endoscopic procedures including dilation of strictures in gullet (oesophagus), botox for achalasia, early cancer resection via gastroscopy, removal of complex stomach polyps, some of them need specialist equipment and supporting teams.

My extensive training journey includes a medical degree from Bangalore University in 2000, followed by 12 years of specialised training in the UK. I further honed my skills through an Advanced Interventional Endoscopy Fellowship at the Royal Adelaide Hospital in Australia and advanced nutrition training at the Intestinal Failure Unit in Salford, UK.
Since becoming a consultant in 2012, I have been a key provider of advanced endoscopy services at Royal Blackburn Hospital, where I also serve as the lead clinician for nutritional-related issues, a very busy endoscopy service and Upper GI cancer. My expertise encompasses a wide range of diagnostic and therapeutic interventions, including EUS, ERCP, EMR, stent placement, and feeding tube insertion.

Personal profile
When not caring for patients, I can often be found exploring the great outdoors with his family. An avid hiker, I have trekked to Everest Base Camp and regularly tackles challenging routes across the UK's national parks. Closer to home, you might spot me cycling through Lancashire's countryside – I routinely participates in charity cycling events like the 'Tour de Manc' to support local health causes.
At home, I enjoys gardening (with a particular interest in growing my own vegetables) and cheering on my children at weekend football matches. These activities reflect my approach to medicine – combining energy, dedication, and care for growing things.
