Regarding your questions on "ease of getting an appointment" the appointment is scheduled so far ahead of time that it was easy to meet. Don't know my satisfaction yet if I had to make an urgent appointment, but I assume it would be timely. Dr Nan is gentle, personable and pragmatic which I appreciate. Doesn't order unnecessary tests which I also appreciate. He does explain my lab results thoroughly. He works in a scary field so I like the way he delivers good, bad or possible prognosis of my health situation. I don't like that I have to pay for parking for less than 1-2 hours, but I know that's out of your control.
