He saved my little boy's life with an atrial septostomy when he was hanging on to life just one day into his life. He has looked after him since. I have to say he is a physician par excellence and I say this as a medical man myself. He is decisive, attentive, compassionate, skilled, knowledgeable and honest. He is there in the good times and bad when things don't go to plan. He makes things happen when others seemingly can't. He is indeed a proper doctor, and I recommend him highly. It is fitting that he works in such a world class children's heart unit, you are unlikely to find better care for your child.
