I had the pleasure of meeting Oliver Warren in his Outpatient clinic for assessment of haemorrhoids post childbirth. After 16 months of conservative management and a lot of pain, Oliver was able to offer a solution (sclerosing therapy) which took immediate effect. Such a relief. He was empathetic, professional and refreshingly frank throughout, showing genuine interest in my situation. I am just so pleased to have been referred to him. He is an incredible asset to Chelsea and Westminister Hospital.

Mr Warren has done it again. I refer back to 16 December 2015 Update: Mr Warren reversed my beloved’s stoma at the end of February 2016. All went 100% well, and he was out of hospital after just a few days! Everyone at C+W looked after him very well, both in hospital and when he got home. It is now 1st July 2016 and all is FINE! As I said in my first post, Mr Warren is clearly a VERY good surgeon and we are extremely lucky to have him at C+W. I understand stoma reversals are not always possible, and sometimes there are problems, but again, thanks to Mr Warren’s excellent original surgery, fantastic teamwork in the interim, and more excellent surgery for the reversal, and first class after-care – all is gooooood. THANK YOU SO MUCH...from very relieved patient, and equally relieved ‘other half’☺ Poppy Smith

Dr Warren is a genius and professional Healer, Surgeon and Consultant. My elderly father was diagnosed with bowel Cancer in September 2015 and was told by another Hospital Consultant he would have major surgery and permanent stoma. Being 84 years old I had my doubts as my father also had multiple health issues, including heart disease. I sought a second opinion, and thank God I did! We were referred to Dr Warren and within one month my father is living without cancer, stoma free!!! From our initial consultation, we were put at ease by his modest air of reassurance and calm. His personality, professional manor gave me confidence in his ability to save/help my father. His enhanced package of care, is excellent, and should be awarded as from beginning to end my father was given first class treatment. He had keyhole surgery, no stoma and within days my father was walking up and down the ward. He now looks years younger, and is happy that he did not die of cancer or surgery. We are truly thankful for Angel Warren. He could be a millionaire if he was a private doctor..However he is devoted to heal and help those less fortunate, without discrimination. He is an excellent Leader, and treats his team like one big family. There multi-disciplinary team is awesome. Long live Mr Warren and God bless him and all his team.

Mr Warren was attentive and efficient and reassured me about my serious procedure. I felt safe under his care and would recommend him to anyone, over any doctor I have seen previously.

Dr Warren listened carefully and sensitively to me and made me very relaxed during my appointment. Very refreshing. I would certainly recommend Dr Warren and feel lucky he is my doctor.
