My recent diagnosis and care with Dr Harsha Kariyawasam was excellent from my initial consultation through to my operation and post care. The combination of Dr Harsha Kariyawasam and my surgeon Mr.Simon Gane at the London Nose & Sinus Clinic enabled my treatment to be carried out smoothly under one clinic. Importantly I was contacted by Dr Harsha Kariyawasam and Mr. Simon Gane throughout my treatment updating me and enquiring how I was. The London Nose & Sinus Clinic team provided a first class service and restored my sense of smell, taste and feeling 100% well. Thank you!

Dr. Harsha is one of the most passionate and highly professional doctors I have ever encountered. Thanks to his hard work I have been able to start my biological treatment for my asthma with life-changing improvements. thank you.

Great insight into my condition followed by successful and innovative treatment. Dr Kariyawasam is a pleasure to deal with and always takes time to explain every detail of the treatment plan and the drugs that will be used. There are no questions or concerns that he will not take the time to address.

I can-not recommend Dr Harsh Kariyawasam highly enough. I have been a patient of his for over 12m and continue to be struck by his extensive experience and expertise, his understanding temperament and fundamentally, his desire to achieve the best possible outcome for his patients. I have and will continue to recommend him to friends and family.

Dr Kariyawasam is so knowledgeable and understanding. He gives so much time and attention and has literally made a huge difference to my quality of life. I cannot recommend him highly enough

Dr Harsha Kariyawasam was very professional and is highly knowledgeable. He left no stone unturned when reviewing me for my sinus condition/issues. He also kept me in the loop with everything he was doing and provided continuous information so I always understood and knew was going on. He also made me feel very comfortable that I was in the right hands. Thank you so much for all the help and guidance.

Brilliant doctor, thank you so much

Dr. Kariyawasam was extremely thorough. Helped explained symptoms and reasons behind medication that’s being given. Nurses in his team were also professional and made me feel at ease.
