Excellent

Thoroughly professional and approachable: an ornament to his profession.

Oliver Warren is outstanding. He did a great job, was both personable and professional. Could not have been happier to be in his care.

I very much appreciate the time Mr. Warren generously afforded me after my admission via The Lister Urgent Care. His affable manner put me at ease from the onset and I was grateful for the time he offered to clearly discuss and evaluate my situation; explain his proposal for a procedure he would perform by fitting me in to the end of his list that day in order that I may, finally, have a definitive diagnosis and treatment plan. At a time of pain and anxiety for me, I felt heard, respected, supported and included in the decision making process and in trusted hands

Having spent most of my life in and out of hospitals, with multiple surgeries; I have met 100s of doctors in my life. From the very first time I met Mr Warren, he was incredibly kind, supportive and open minded about my complicated case. He helped me personally through every step of the exploratory phase and maintained his incredible kindness and professionalism through a highly successful surgery, for which I am en eternally grateful. Mr Warren is one of the best doctors I have ever met and a personal hero of mine for what he did for me.

Very pleased with my continuing recovery

Superb specialist. Highly competent and communicated very well. Cannot recommend highly enough.

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!!

He did first my surgery through the nhs and I paid to have him privately to get my reversal done sooner because I was very happy with my first surgery

He's totally professional, extremely knowledgeable and very personable. He inspired total confidence in me and was the specialist I wanted to do my procedure as it was fully explained to me how complex my medical condition had become. Straight away I knew he could do the job properly. The results have been outstanding so far and I would have no hesitation recommending him to anyone with a similar condition to what I had.
