    Dr Sunthar was excellent in all manner of my treatment right from my very first appointment. He clearly explained all the tests that would be needed to come to a diagnosis. He prescribed medications at my first appointment to help ease my symptoms- and they have done so. Throughout all stages he took the time to clearly explain the results of the tests and how they impacted my treatment. Everything was done efficiently and without delay. Although he is a very busy cardiologist his personal presence in all diagnostic tests made me feel lot more comfortable and his personal care and kindness really amazed me. Within five days of the diagnostic tests he diagnosed the problem and advised me for the most appropriate treatment. During all this period whenever I called him his response was immediate and he gave me advice accordingly. He is a very experienced cardiologist and very polite, kind and very caring and I would like to personally thank him for his precious time during my tests and treatment and I will continue with my treatment on his advice. At this time I don’t want to forget about his secretary Kiran who has been amazing in being available whenever needed and in explaining and responding to my queries. Thank you.

    I only have good things to say about Dr Kanaganayagam. He has always explained everything thoroughly and always answers messages when I have additional questions about my treatment. He conducts himself professionally with a kind nature - you can tell he genuinely wants you to get better. I would highly recommend him.

    My whole experience with Dr K and his team was excellent. Everything was clearly explained beforehand and I was given very clear feedback after the procedure. I was not looking forward to it but was made to feel relaxed. I had a sedative and remember an insert put in my mouth and then Dr K saying the procedure was complete. I appreciated nurse Anja arranging to call my wife soon after the procedure was successfully completed. Many thanks.

    Everything was explained and the nurses ensured I was very relaxed. I found Dr K very approachable and professional. I was given a sedative injection. I remember biting on a plastic insert and then Dr K saying the procedure was complete. I was soon back to normal. Everything in the Clinic was comfortable and professional. It was a nice touch that nurse Anya had arranged to phone my wife when the procedure was successfully completed. Many thanks.
