Feedback on Dr. Kazila Bhutia and Dr, Ada Ang from KKH.

Dear Mummies, I am confused whether to go to NUH or KKH. Currently going or checkups under subsidy in KKH. Liked KKH consultation, timing and facilities. Do anyone have experience with the doctors Dr. Kazila Bhutia or Dr. Ada Ng from KKH? I had mild rectocele and GDM for the first pregnancy. Any other suggestions for doctors in NUH or KKH for my case. I prefer to choose an experienced consultant to a busy senior consultant. Please help :)
