I recently had a very embarrassing issue with regards to a sensitive area of my body, I visited Dr Jarvis through my BUPA plan and chose him based on his excellent reviews and skill set. I was not disappointed, Dr Jarvis was friendly, professional and explained everything throughout my two visits including a procedure. Im pleased to say my issue was resolved and I was reassured if the problem did persist or return to make contact. Again friendly, professional and very reassuring, overall I was very pleased with the service and his assistant Victoria was also very helpful and professional along the way.
Mr Jarvis was extremely professional and dedicated. He wasted no time in arranging tests and scans to determine the cause of my discomfort. He was very clear and transparent about the treatment I received. I immediately received reports outlining the procedures and their findings which was extremely comforting. His dedication knew no bounds, when he personally followed up reports needed from Radiology. This, combined with the constant follow ups from his secretary Victoria, resulted in a prompt diagnosis, enabling me to continue with a previously booked trip abroad. Absolutely brilliant personal care.

Thank you for your review. Very Best wishes for your upcoming trip .
The treatment i recieved was delivered professionally and promptly I recieved excellent pre and post operative care
Dr Jarvis was very clear and concise about my tests and results. He explained them in layman terms and was helpful answering my questions. I found him to be very approachable and easy to speak to. One is the best experiences with a consultant, highly recommended.
I have seen Dr Jarvis both in the NHS and private sector. He is excellent, very thorough, kind, reassuring and informative. I travel over 50 miles to see Dr Jarvis, he is fantastic doctor and I highly recommend him.

Thank you for taking the time to leave such a positive comment.
I recently saw Mark as I had a number of gastro concerns. I was able to see Dr Jarvis within a few days which was great and he listened to all of my concerns and made a clear plan of action. Following my results I was called to book in a follow up and Mark again saw me very quickly. He explained everything clearly and was extremely helpful. I would not hesitate to recommend Dr Jarvis.

We are so pleased that you had a positive experience, Thank you so much for the feedback.
Excellent physician. Very clear in advice and helped me out a lot.

Thank you for taking the time to leave a review. We are very grateful.
Dr Jarvis is incredibly professional, unassuming and an expert in his field. I found him very approachable. He is a real credit to the industry. I was very nervous for my procedure but he made me feel as comfortable as possible by taking his time to explain what was happening / going to happen.

It is perfectly reasonable to feel apprehensive before an invasive procedure like a colonoscopy, and we work hard to make it as easy as possible. Your kind words are very much appreciated.
Thank you so much for a good experience
