It is so hard to choose when both seem good in their own ways, and I think many of us have been in that same position of feeling torn between two doctors we liked. A friend of mine saw Dr Choo Wan Ling for her second pregnancy and she said she always felt very well taken care of, especially because the staff were so warm and helpful during the more anxious appointments lah. Since you mentioned the staff experience matters to you, that might be worth weighing quite heavily, because you will be seeing them just as often as the gynae herself throughout your whole pregnancy journey.
