Riku, if first time pregnancy try KKH Private Suite mah, they will assign doctors if you don't know who to choose or you can go into their website to look through their panel of doctors and request the gynae when you are at KKH....they actually have the best facilities for infants and babies. The normal women's clinic in KKH tend to have long queues and waiting time. Other Private hospital also send their patients to KKH for complicated issues.
Alternatively if you are looking for recommended gynea, see who the girls are using here lor. I'm with Dr Benjamin Tham, he is a very gentle, soft spoken and very friendly doctor. Usually tries to help patients save money also by not doing unnecessary scans when not required. you can google him online he has lots of good comments and recommendations about him. He is with TMC though. I had my last birth there no problem ahh, nurses in maternity ward were all very nice and helpful as well. I had a really good experience there although there were mixed reviews online about TMC itself. You can see a thread about DR Benjamin Tham on this Motherhood Forum too.....go and check that out.
