My boys saw Dr. Chan several times. He is very nice and patient, especially for the kids. He smiles and plays with them. He will try to explain the case with you in details. I feel comfortable to see him. In all, a good doctor!
But his medicines seem not very work on my boys. And I may think he is too young that experiences seem not enough(maybe it's not fair!).
He will give 3 days medicines normally but you can request and discuss with him.
