Hi Victoria31,
Did you mean TC Chang at TMC? Yes he is good. He is fairly flexible and willing to support women who may want a drug free birth. Happy for women to be off the bed and active etc, if this is what you are looking for. Equally happy for women who may not want that.
There is also Paul Tseng. He is also at TMC and brilliant as well.
Thomson Medical Centre is great. Unfortunately their labour rooms have no natural light and they only have one room with a tub in it. Others have showers only.
The staff in L&D are wonderful as well.
Perhaps you can think about what type of experience you are after, then go from there. There are two different kinds of care here in Singapore.
Active management and expectant management. Both are equally important and neither one is right or wrong - just different.
Active management OB's tend to have higher induction rates, high c-section rates, do routine testing and scans and before I get flamed for saying this

, this is great if this is what you want. However there are many women out there who want a more expectant approach. That is no scans, testing, go into labour spontaneously, active birth etc.
An active management OB will do things routinely on the "what if" chance that there is a problem in the hope of preventing it where expectant management OB's will take more of a "lets wait and see" approach.
Always a great idea to meet a couple of OB's. You will find one that suits your needs.
Good luck!
Tania
