My passion has always been helping the patients with the most complex and difficult problems - the ones that have run out of options. I have dedicated three decades to becoming an expert in the care of patients with complex rectal cancer and inflammatory bowel disease like UC and Crohn's disease. In particular, my special skill is re-operative surgery for the patients "who cannot be fixed". When nobody can help, I will always try.

Personal Interests

I am passionate about vintage cars and have raced them all around the world for many years. These days I don’t do so much but I follow any form of motorized competition! I am an armchair sports enthusiast and lifelong Manchester United fan. I am also a keen amateur – but messy – cook!

Care Philosophy

I believe I can best serve my patients by learning about each one personally. Surgery is about real and unique people who have a problem - they're not just a disease. I need to know what matters most to my patients so I can help the best way possible. That's why I like to hear their story!
