I found Dr. Mark O'Donnell to be very professional and he explained the procedure clearly and made me feel at ease. Any questions I had were answered comprehensively and he had a very friendly manner as well as being very experienced. My second follow-up appointment actually occurred earlier than I expected which was an added bonus.

Professor O Donnell what a truly exceptional professional
Professor Mark O Donnell, what a dedicated, truly genuine professional with a modern method & outlook on giving the best outcome for your vein treatment. Thats my experience over the past year having had veins treated on both legs. He has really given me back my confidence and a new lease of life, now able to wear shorts on holidays something I could never do! The best in the business in my opinion.

The professionalism Mark and his team…
The professionalism Mark and his team showed were beyond my expectations. The minute I met Mark he make me feel so comfortable and explained the procedure I was about to have and everything so well. The surgery was quick and effective and the results are great. When I came back up for my post op review 12 weeks later he showed me how successful my surgery was and gave me some tips to look after my legs and veins for the future. I would honestly recommend Mark and his team 100 times over as I feel it was the best experience I’ve had in a hospital setting.
