I also had an exceptional experience with Dr Doo over the past 5 months, and he helped deliver my baby boy around 2 weeks ago at Matilda. This was my second pregnancy, but first with Dr Doo, and comparing him with my first Ob/gyn (who I thought was also very good) I thought he was extrememly professional, thorough, kind, knowledgeable and approachable. I had a fairly smooth pregnancy and didn't really have to call on him for any additional help, but he continually reassured me that if I needed anything to call him straight away. In the delivery room, he gave me a lot of confidence in his ability to get the job done, and my husband also felt very reassured by him. Honestly, I can't recommend him enough, and if we decide to have a third child, and are in Hong Kong, I will definitely go back to him without hesitation.
For the record, the longest I waited to see him for a consultation was an hour. He also does a full scan each consultation (much more detailed by other Obs I have seen, which has actually been a few), explains everything that is going on, and I learnt much more from him in this pregnancy than prior Obs. As he does scans every visit, each visit is $1900 (which we were not fully covered for), but when I was deciding which Ob to go with, I felt most confident with him. We thought the increased cost was a small price to pay for the level of service he provided, and the confidence he gave me to get through the whole process. I found that he is also very open to go with 'your' birth plan. He was quite 'pro' natural delivery, never pushed for a c-section, and listened to what I wanted. My husband and I were extremely happy with him. Good luck in your decision.
