I had a faultless experience with Mr Warren at One Welbeck which is a great facility. Mr Warren and his support team are impressive - professional, informative, clearly knowledgable, whilst offering a friendly context to everything. Should I need future treatment in this area of medicine I will request to see Mr Warren and his excellent team.

As a Canadian expat living in London for a few years, I was concerned about a needed surgery. From my initial appointment, I realized I was with a highly experienced, excellent surgeon. An important factor is that this doctor is both intuitive and understanding of patient anxieties . His charming , cheerful personality is reassuring and allows for a comfortable dialogue when necessary. He is informative and accomplished , absolutely stellar. You are fortunate to receive a referral to Mr. Warren . Gemma , his admin assistant was extremely helpful and informative in ensuring a positive experience and good outcome to the administrative aspect of this surgical process. I am very happy with the medical treatment I received and consider myself very fortunate to have been in their care .

Very friendly, and approachable to talk to about what are often somewhat “awkward” topics (!) - his recommendations and treatment plan were both reassuring and effective, and it was overall very good to have someone like him - knowledgable, supportive, approachable, and clearly skilled.

Mr Warren is an outstanding doctor. Highly skilled, of course, but also compassionate and kind. Surgery is never something anyone looks forward to. But, Mr Warren made the whole experience as positive as it possibly could have been.
