Thank you for the kind words
Dr Selva Theivacumar was professional and helpful from the beginning when consulting me on my varicose veins. He gave an excellent recommendation on what was possible and necessary in a tailored treatment plan to achieve my desired outcome. The team and him always made sure I was comfortable and clear with each stage, along with being friendly, knowledgeable and vigilant in the lead upto the procedure which helped put my nerves at ease. In the after care I was well looked after and given instructions on how to look after myself at home along with any limitations. I am delighted with the results - many thanks to Dr Selva Theivacumar and the team at Hendon Hospital!

Thank you for the kind review
We had a visit with him after my mother had vascular surgery (also done by him) and he saved her life. He was very professional and intelligent and we couldn’t be happier with him.
