I was followed by Dr. Yu (all the way to my C-section), He is the incharge of the maternity unit in Union, and quite good for both checking and C-section. U can see my sharing for Union C-section in my BB website
Dr. Sin is good too, as he was following my Oscar and Structrual Checking (Dr. Sin was arranged by Dr. Yu for me becaus I did both tests in Union). He is very detail and professional. My room-mate in Union (C-section in June) was followed by Dr. Sin for C-section, and she said he is good too.
