Please help! Jacqueline Jung or Serene Thain at KKH?

Hi mummies! Hope you can help with my dilemma. My current gynae is Tan Shu Qi at KKH. I went under private cause I chose her as my gynae. She was so sweet, kind, and soft but today at my appt she told me she is away during my EDD so I have to choose between 2 doctors she recommended to me. Has anyone experienced with Jacqueline Jung or Serene Thain? I try to search Jacquline jung's review but can't find much about her.
