From initial consultation through surgery and post operative care, Oliver Warren was very professional and reassuring, explaining all steps of the process in easily understood detail. I was fully confident he would be able to carry out what was potentially a complex robotic hernia repair. His extremely high level of experience, skill and care ensured a fully successful outcome. I am very grateful I was referred to him and couldn’t be happier with the end result. I can’t think of a single thing that could have been better and cannot recommend Oliver and his team highly enough - thank you.

I recently had an inguinal hernia repair performed by Oliver Warren. It was a particularly large hernia that I had ignored for too long - nevertheless Mr Warren was able to perform via a minimally invasive robotic procedure, which aided a swift recovery. I have been very impressed by Mr Warren's surgery and overall care. Clearly, a highly experienced and skilled surgeon - the proof is in the pudding!

I had been struggling with abdominal issues for some time, and Oliver was recommended to me by a number of other specialists. As an actor and model, these issues were threatening my future career and I was very concerned. Oliver examined me thoroughly and went on to explain all the options that were available to me, highlighting not only the possible benefits but also possible drawbacks. Several other doctors had offered to 'attempt' a specific form of corrective surgery on my abdomen, but Oliver wasn't willing just to 'take my money' if the chances of success were minimal... and minimal they were; he explained why too! Together we made a decision not to proceed at this time with corrective surgery, as the risks involved outweighed the possibly of success. However, these abdominal issues were then compounded by a double hernia (which definitely needed operating on!)... and I knew straight away that I wanted Oliver to perform the surgery. He'd earned my trust by not simply going ahead with the earlier corrective surgery, and he also understood how important the surgery was to my career and for a certain aesthetic to be maintained. Pre-operation communication was fantastic, and I arrived at One Welbeck in London at 7am... I was then back home (in Leicester) by 3pm! The result... incredible. A week later I competed in the World Coal Carrying Championships, and within 2 weeks I was back in front of the camera. He has done an incredible job not only in repairing the double hernia, but in improving the aesthetic of my abdomen. I can't recommend Oliver enough, and (if I need to any more abdominal surgery) there's no one else whose care I'd rather be under.

The whole experience was very easy and relaxed and I had total confidence in Dr Warren which made it an awful lot less stressful. Very happy with all the follow up and the recovery.
