Mr Warren has a pleasant, understanding manner but at the same time exudes a reassuring air of professionalism and competence. The hernia repair which he carried out on me was successful and I experienced far less pain than expected in the immediate aftermath of the surgery.

I met Mr Warren for the first time in July 2022, first he explained in great detail excatly what he could do for me and how he would do it. He then made it clear what he needed from me to ensure a successful outcome. I particularly liked his comment about how he always ensured success, "my careful and detailed planning" Mr Warren performed the operation in the Lister Hospital on the 3rd November 2022. It has been a great success, It has relieved the major pains I suffered from, I have been able to eliminate the pain killer I took, and in short it has given me my life back. No words can express my gratitude and that "detailed planning" certainly made it work. The professionalism, the skills and the courtesy shows why Mr Warren is world class.

Mr Warren was recommended to me by another respected surgeon. I was extremely happy with Mr Warren who explained everything in more than sufficient detail. As regards my surgery this was a complete success and the post operative advice and care I received exceeded my expectations.

Mr Warren came to me on the highest recommendation and my experience of him was outstanding. Every time I have met him I was greeted warmly and made to feel at ease. In my consultations he was direct and clear in his explanations of my condition and the surgical procedure necessary, listened to my concerns and answered my questions. He was confident and supportive and his skills were very apparent by the smooth and problem free operation that was 100% successful. The aftercare during my time in hospital and in the following consultation was also excellent. I would highly recommend Mr Warren!

Mr Warren was both reassuring and compassionate as I entered to meet him on my first visit. He walked me thru the procedure of tests I would be facing and instilled in my a great deal of confidence that I was in good hands. My second visit he was again reassuring and ran me thru the facts. A good result on the tests not withstanding, I am confident I would have felt the same way with his care on bad results. He was professional and put me at ease with my visits. I would greatly recommend him to anyone that needed his services. Regards David
