Welcome to my website!

I have set this site up to help you understand some of the common gastroenterological conditions as well as the investigations and treatments that you may receive.

About Dr. Clive Onnie

I qualified at The London Hospital Medical School in 1996 with a distinction in medicine and a first class honours degree in pharmacology. I subsequently worked in several world leading hospitals including St Mark’s and Guys and St Thomas’ Hospitals. I undertook a Masters in Medical Science at the Hammersmith hospital in 2001 and completed a PhD at King’s College, London in the genetics of inflammatory bowel disease where I was awarded a Digestive Diseases Foundation Research Fellowship.
