Dr Karagiannis is efficient, professional and friendly. Combines expertise and willingness to listen and discuss, answered questions in a clear and easy to understand way. I highly recommend him .

Incredibly thorough, logical and methodical in his thinking. Made a lot of sense and had a great idea for how to progress forward.

Very clear, quick, and efficient

Our son had been experiencing cardiological problems for several years and we struggled to make any progress towards a diagnosis or treatment until we saw Dr Karagiannis. Dr Karagiannis undertook a number of tests and was able to quickly reach a diagnosis of hEDS and begin treatment. He also liaised with other medical professionals to ensure our son received physiotherapy and GP support. He has continued to provide support for our son, including providing written evidence of his condition that we required for school and exams. We are tremendously grateful for everything he has done and continues to do.

Pleasant and knowledgeable

I was very pleased with my experience

Very professional

Dr Karagiannis is a wonderful, caring and expert cardiologist. I went to see him following chest pains and referral to see a cardiologist. He shows great empathy, kindness and explained the results of the ECG, echo and other tests with expertise, putting my mind at ease. I would highly recommend him as one of the top cardiologists in London.

Dr Karagiannis put me at ease despite my concerns, I even received a follow up call after I raised a query regarding next steps for treatment. I have no hesitation in recommending Dr Karagiannis to others.

Great specialist, friendly, take care of patient!
