I really feel for you, having to switch OBs so close to your delivery is so stressful and unsettling. I don't have a personal experience with Dr Wang Junjie myself, but I have a friend who was also transferred to him at KKH and she said he was calm, thorough, and made her feel very at ease during her consultations. She felt well taken care of throughout and had no complaints at all about how he handled her delivery. Hopefully you'll have a smooth and positive experience with him too, and wishing you a safe and easy delivery ahead!
