Dr Gregory was very helpful and professional. During my follow-up appointment, he asked all the necessary questions regarding my health, including whether I still have any issues with my bowels, stomach, or diet. He also carried out a quick scan of my bowel to ensure everything was normal. I was very pleased with his attention to detail and the helpful dietary advice he provided. He is a very kind doctor.

My gastro consultant, Dr Sebepos-Rogers, gave me ample time during my appointment today to ask overdue questions, and he explained matters to me in detail. It is very important for a patient to be able to trust a physician and to feel that everything is explained well. During my 2 week stay in hospital, I really had not been given enough facts about my condition despite asking, and therefore I was very anxious to be seen today. He will also follow it all up with a letter in the next few days. I felt fully understood by Dr Sebepos-Rogers and value him highly as my consultant.
