Dr Yiannis is very willing to help, to listen and address all of the concerns and make sure nothing is left and you are getting the best of the visit
Dr Yannis was once again brilliant! He assessed our 4 month old thoroughly, and answered all our questions. He was professional and at the same time kind and warm, and very reassuring. We felt we are in great hands. We will be coming back for our check ups.
Yiannis has seen my children for years and I highly recommend and trust him.
It was a very easy and smooth experience — I made my booking and payment online, so I didn’t need to call the clinic at all. Everything was perfectly handled online, and I even received my invoice right after booking. I met Dr. Yiannis for the first time, and he was incredibly kind and patient with my son. The whole experience was very positive — the doctor’s office is lovely, well equipped with toys for my 2-year-old, and the assistant was also very kind. I’m really glad we found him!
It is a privilege working alongside Dr Yiannis Ioannou who is an outstanding General Paediatrician with sound knowledge base and exceptional diagnostic skills. He has a refreshing compassionate energy that is contagious. His has a distinguished educational portfolio and has successfully revamped the curriculum for our Imperial College medical students. I can wholeheartedly recommend Yiannis to any family seeking excellent paediatric care.
