My son, who is now 3-1/2, has seen Dr. Tam since birth. And we requested him to be our doctor since my daughter was born in the hospital, she is now 2-1/2. He has always been responsible, responsive, informative, professional, and good with babies/toddlers. He came to see my daughter everyday for the 4 days that we were in the hospital. When she was nearly 1, she was admitted to Canossa for Rotavirus, and we spent 2 nights (including Christmas eve) in the hospital. Again, Dr. Tam came to see us twice a day even though it was holiday season. Throughout the years I have paged him several times, he always returns my calls promptly, and I have even spoken to him while we were out of town on holiday when the kids came down with something.
He is a very popular doctor, you'll see him on TV and magazines, etc. but I do feel he takes the time to see us properly. Especially at the Canossa baby clinic, I feel he is far more relaxed about time when he's seeing the well babies.
Several times we've not been able to get an appointment with him because he's fully book, in which case I speak with the nurses who then relay the situation to Dr. Tam, and then he either decides to squeeze us in or to tell me to pick up some medicine either at his clinic or at Canossa.
Even with an appointment, it's not uncommon to wait for over an hour as he usually gets delayed or called away. The nurses do their best to keep you informed, and it's always a good idea to call (several times) before you leave the house to check how late he will be.
Overall, I think he's a great doctor and a nice person. Recently we've started seeing less of him as I'm trying to go a more natural path instead of relying on western medicine all the time. Sometimes I do feel he's a bit liberal with the medicine, but I feel better taking the medicine home with me and deciding not to use it, rather than not taking the medicine and making another appointment with him when the kids get worse (both situations have happened to us before).
He's very well-dressed, and on first impression, he seems too stylish to be good with babies, but he's actually very gentle and quite good at baby talk!
Every mother and child will prefer a different style (and price range). I think Dr. Tam is a good doctor to give a try.
