From my first consulation with Mark I have felt confidence in his knowledge, experience and ability. He is clear, thorough, precise and to the point whilst still maintaining a genuine air of care. Thoroughly recommend him.

Took time to listen and take history. Explained what the problem was and investigations I needed.

Professor O’Neil’s manner was gentle and non intimidating. He addressed all of my concerns with clear explanations and useful information.

He explains every symptom and findings in detail, and explains with words that we can clearly understand. He takes huge effort to look into case to make sure every thing is all good. No doubt about his expertise- would highly recommend him.

Pr Mark O'Neill was very attentive to my symptoms, explained to me in details what could be done to understand it better and recommended follow up exams to complete his diagnosis. I felt all was done to help me and get to the bottom of my symptoms but also to look longer term at my health. Very good experience.

Expert in his field, I have total confidence in the diagnosis and care received.

Reassuring help on hand

I have been a patient of Prof O'Neil for a number of years. He is both completely professional and personable. I have complete confidence ih his judgement.

I came along with a friend of mine who doesn't speak English well to meet Prof O'Neil. I can say he is one of the best doctors I ever met, he clearly explained the problems and the solution in a simple way for the patient to understand. I highly recommend the Prof and would like to thank him for helping my friend.

Always excellent.
