It's a common practice for doctors to charge more depending on the room (even though the medicine and service is the same). My friend's OB does the same thing.
I am currently 7 months pregnant with my second baby, and Dr. Joe Chan is delivering my baby at the Sanitorium via C-Section. (note this is JOE YM CHAN not Joseph Chan, another OB). Dr chan does more natural deliveries, and seems to be very respectful of patient's wishes. In my case, I specifically requested C-Section because complications with my first and I don't want to experience that again.
So far, I'm very impressed with him. He has always been available when I needed him within 24 hours, usually responding to me through email within a few hours. Haven't had any emergencies, just basic questions and concerns. I have a lot of questions and he always takes the time to answer them. Obviously I haven't delivered yet so as far as his service during delivery, I can't comment. will share my delivery experience after the baby is born in November! Waiting period during office visits are not usually that long. at most I've waited 10 minutes. Although he has a lot of expat patients, I also noticed a lot of mainland Chinese patients.
Overall, the feeling i get is that he is a competent, professional, and pro-patient doctor.
