I really feel you on this, it can be quite nerve-wracking trying to find the right gynae, especially when stitching matters so much postpartum. I don't have personal experience with Dr Tan Poh Kok myself, but a friend of mine did see him and she said she felt well taken care of throughout, and her recovery was quite smooth with no major issues. It might also be worth asking around in your hospital's patient support groups or calling the clinic directly to ask about his experience with deliveries lah. Hope you find the reassurance you need soon, and wishing you a safe and smooth delivery ahead.
