I had 2 emergency C's, that last one with TC Chang (the first was in the US). He is EXCELLENT. The above poster is spot on - he cares about the patient, loves birth plans, and is a very warm, friendly guy ... exactly the sort of OB you want in the operating room. I delivered at Mt E with TC Chang, and Dr Belinda as the paed for my newborn. TC delivers at TMC (where his offices are), Mt E and Gleneagles. Just tell him which hospital you prefer. Coincidentally my newborn in Singapore was in the NICU for 2 weeks after the emergency C (no complications related to the birth, she was just preemie by 6 weeks) and the Mt E NICU is second to none - babies from other hospitals are routinely sent to MT E because it is the best one in Singapore, and the staff/medical facilities are outstanding.
I was in your situation about 1.5 years ago when pregnant with my second (and jsut arrived in Singapore) and I decided on an elective C just like you (which ended up being another emergency C anyway!) and I found the choices I made (above) re the doctor and hospital I chose were first rate (and I'm fussy). I have no regrets whatsoever. Good luck.
