Mr Oliver Warren

Mr Warren is as good as it gets. I knew I was in very safe hands and my high expectations of the outcome of my surgery were met. Nobody does it better.

I really appreciated the very human and personalised approach.

From start to finish I felt very happy with all aspects of my treatment which I felt was to the highest order

Excellent, compassionate, thoughtful and kind

Mr Oliver Warren is an outstanding surgeon. He focuses on the best outcome for his patient. He left no stone unturned during the diagnosis stage and he kept me very informed throughout the journey. Once the decision to progress with surgery was made, he acted really quickly and to the best of my care. Evidence of his exceptional surgical skill is the fact that I recovered really quickly, with no complications, no iliostomy and hardly any discomfort. I truly feel very fortunate having Mr Warren as my treating surgeon and I will ever be thankful for his skill, care and excellence.

Mr Warren has kept me fully informed throughout & attentive post op

Mr Warren is a phenomenally good doctor; you immediately feel completely safe in his care. His knowledge, expertise, kindness and utter professionalism are second to none. Mr Warren has a brilliant team around him including Mariana Goncalves who is the GI/Colorectal Clinical Nurse at The Lister as well as the team on the 5th floor.

Great experience from start to finish. Mr Warren and his team made me feel very calm and cleared up and questions I had to leave me feeling less anxious about the operation and confident about the result. Mariana was great and being able to meet her pre op to run through all last minute thoughts and issues was fantastic she has also been very communicative and helpful post-op.

His very professional and an excellent dr

When first meeting Mr Warren for my first consultation, I immediately felt his genuine, professional and confident approach. Everything was explained in detail and my questions answered both honestly and in total, this was most reassuring. Pre and post surgery consultations were made to be as easy as possible for me. The post surgery discussions were relaxed and informative, my questions were answered in detail and in a way that I could understand. I honestly felt I was talking to a professional person I had known for years not just days!!
