Mr Lewis is most professional and engaging with a lovely caring manner putting you at ease . Providing you with all the information you require both pre and post op and always ready to discuss any concerns . Highly recommend, was excellent for more tricky keyhole surgery .
First class. Kind, compassionate and really listened. Most important was the cure!
A very good experience, straight forward explanation prior to the op, and execution as planned.
I thought the hospital could have been a little more helpful when I had some rather severe post operative constipation .But I was very pleased with the pre-op /op /post-op treatment i received from Mr Lewis.
I would advise anyone to put their care in Mr Lewis' hands he is efficient, professional, highly skilled, very kind and understanding. He has a great sense of commitment before and after procedure, this shows especially in his after care, I have has private surgery before but I have never received a emailed letter written after the procedure, on the actual day of surgery, explaining how the surgery went and what was accompliced , this was followed by an in depth emailed letter recalling my follow up appointment. I would recommend Mr Tryston Lewis most highly.
Dr Lewis explained everything in detail and in a manner that I understood which made it a far easier experience. Any questions that I had were answered and nothing was rushed. Dr Lewis cares about his patients and their well being.
Very competent and professional surgeon. I would highly recommend Mr Lewis.
I’ve received incredible care throughout my experience. Dr Lewis is probably the best medical professional I’ve seen in the UK — he took the time to explain everything clearly, and the quality of care has been outstanding. What stood out most to me was how personable and approachable he was. He made it easy to talk openly, encouraged questions, and I never felt that my time with him was rushed. Every interaction felt relaxed, comfortable, and genuinely caring. I’m really happy that I was referred to Dr Lewis and that he was responsible for my care. Please pass on my sincere thanks and appreciation.
Mr Lewis is an excellent colleague. The patients I’ve referred to him have always had a positive experience.
