Reviews
Dr Warren is a great surgent. I recently had to undertake 2 surgery in one ,where he was the lead surgent and him and his team did a fantastic job. No big scars where made. He is very professional at what he does and takes good care of his patients.

Im terrified of doctors/ hospitals but Doctor Warren put me at ease straight away. A very friendly, approachable and caring doctor. Listens to all your concerns and answers your questions thoroughly. By the end of my consultation I felt like I was sitting with a friend rather than a doctor. If all doctors were like him, I would no longer have a fear of having a check up! Rest assured you will be in great hands, if you're lucky enough to get him. Maria Uchi
I was referred the Chelsea and Westminster hospital and to Oliver's team. I had possibly over researched and over worried some aspects of a relatively minor problem but Oliver was patient in addressing and allaying any matter - pre and post operative Oliver maintained confidence and positively with constant assurances that he would only act with my full knowledge and consent. 10 days after my surgery I had some genuine concerns, I emailed Oliver to let him know this and also to advise I arranged a GP, he replied almost immediate and invited me as an outpatient overbooking and to not trouble my GP. Once again Oliver provided the reassurance I was seeking. I gave Oliver additional information to another condition that ultimately exhibited itself post operatively. This has led Oliver to want to address this matter further to benefit future patients. I'm glad I have provided some insight that Oliver can look at further in his very clear desire to have the patient at the heart of all he does.
Genuine thank.
Mr Warren is one of a new breed of Doctor, who in spite of following in the footsteps of a highly hierarchical system, has made his clinic his own. I felt that he understood my concerns totally and utterly and that need to see him became a partnership between patient and surgeon.
He is by far one of the nicest and most patient and understanding doctors I have ever met and have no reservations in recommend dung him and his excellent team.
I Felt Doctor Oliver Warren did a fantastic job for me.
I had spent some years in discomfort and inconvenience with prolapsed arteries/haemorrhoids,rather afraid and embarrassed to deal with it.
i was seen with care and attention throughout from my first consultation
through to my aftercare checkup.
I did appreciate Doctor Warren seeing me before the operation and explaining what
he may do to sort my problem out for me;explaining his aim, in the procedure would be to operate having the least impact on my body, with having the most effect, there being a choice of techniques he may use.
This he has achieved with marvellous effect; i'd forgotten what it was like, but i now
am functioning properly; Life changing for me!
Many thanks to Doctor Oliver Warren and a great team of dedicated people to enable me to get this done and an assurance by him that he would be there should i have any need in the future.
