hernia operation. Success. speedy recovery and signed off after 4 weeks.Doctor Warren easily trusted backed by detailed history of operation results.Perhaps bedside manner a little peremptory but put that down to workload. On follow up both friendly objective and sensible. All in all would positively highly recommend him and he did an extremely good job getting me sorted out,healed and back to normal in short order. secretarial help when wanted efficient but not easy to access at ones convenience always necessitating a left message and then return call but polite and helpful on line. Thank you. George Gordon

Mr Oliver Warren is a highly skilled surgeon with a wonderful calm bedside friendly manner, who is extremely knowledgeable on so many levels. I am so happy to recommend him to any patient as I know you will receive the most wonderful care. His has also collected a wonderful support team who are also incredibly talented especially his anaesthetist Gabriella. Mr Warren operated on myself and I recovered really quickly. My wife also received treatment from Mr Warren for a cancerous 4cm tumour in her colon which Mr Warren skilfully removed and he did such amazing work that she didn't need a stoma bag, which made her really happy. She also recovered really quickly from the operation. We both really cannot recommend this gentleman enough you will not be disappointed. Mr Warren is a surgeon we would always be happy to recommend, we would not go to anyone else.

I was a reluctant patient with a recurrent hernia (not Mr Warren’s work). I had seen a couple of other surgeons whose descriptions of their repair techniques left me running for their various doors. But this was not so during my initial consultation with Mr Warren. He understood immediately what I was saying and his clear explanation of his proposed techniques led me to sign up there and then for the repair. I wasn’t wrong to do so. Now six weeks the other side of the operation I can confirm that it has all gone very well. He was very clear about what to expect along the way which was very helpful. He is a rare beast - a skilful surgeon with a bedside manner! He works alongside equally professional and friendly people including his brilliant of anaesthetist Gabriella and a faultlessly efficient office team. My thanks to them all.

I was referred to Dr Warren by my GP after presenting with severe haemorrhoids. I underwent a Rafelo procedure at the Lister and, in a remarkably short amount of time, am symptom free. The whole process from start to finish was efficient, friendly and filled me with confidence. I can't recommend Dr Warren and his team higher.

Oliver Warren performed a laparoscopic inguinal hernia repair on a sack on my right side on the 1st of December 2023. The procedure had had to be postponed for various reasons and the sack had become considerably enlarged since first appearing in the preceding August. At the consultation prior to surgery Mr. Warren explained very clearly precisely what would be involved and advised that pain relief would be needed for 5 days after the procedure and that dressings would be able to be removed 7 days after. After 6 weeks he anticipated that I should be able resume vigorous exercise. It is now 7 weeks since the repair and all of Mr. Warren's timings have been accurate to the day. I am back in the gym and have begun to return to high intensity training in the past week without any discomfort. Also, the small incision scars have begun to fade away and the scar tissue around the repair itself is getting noticeably smaller. This entire episode could not have gone better and I am hugely indebted to Oliver Warren for getting me from being painfully incapacitated back to full health in a mere six weeks.
