"I am proud to work at Spire St Anthony's Hospital. It has excellent facilities including state of the art integrated theatres and a dedicated critical care unit."
I have been a Consultant Colorectal Surgeon at Frimley Park Hospital, Surrey for over three years. I have a specialist interest in minimal access keyhole and robotic bowel cancer surgery, helping continue the excellent work that has been developed in this area at Frimley Park Hospital.
Specialist interest in: Management of colorectal cancer; Laparoscopic and Robotic bowel cancer surgery; Transanal micro-surgery for polyps and early rectal cancer; Colonoscopy and removal of polyps; Diagnostic endoscopy; Emergency minimally invasive surgery for acute abdominal conditions; Haemorrhoid surgery including injection, banding, traditional haemorrhoidectomy, stapled haemorrhoidectomy, HALO and Rafaelo, Proctology: fissures, fistulae, abscess and sinuses and Prolapse and incontinence.
I went to medical school at St George's Hospital University of London and completed my higher surgical training programme in London and Surrey, following a period of research in colorectal cancer. In addition to my expertise in bowel cancer, my practice has provided me with great experience managing other benign bowel disorders including, anorectal problems, inflammatory bowel disease, irritable bowel disease, anaemia and pelvic floor disorders.

Having played a lot of cricket and rugby, I enjoy following both sports avidly.
I have a love of music, having played the cello for my Medical School orchestra. Whenever possible I enjoy visiting the Royal Opera House with my wife to watch operas. I also enjoy listening to all kinds of music, especially when I operate. I have a particular affinity to rock music. I especially enjoy listening to music from groups such as Pink Floyd and Genesis, having seen them in concert.
Most of my weekends are spent helping my children with their activities. However, we manage to make time to work on our allotment as a family.
I also enjoy travelling around the world.
