"I have been going to Dr. Kwok for years. She has always been able to fit me in. She takes my concerns seriously and I do recommend her. I had an issue previously with a PAP, where it had to be redone. The lab billed my insurance twice, resulting in a bill stating I owed for the second one, because my insurance only pays for one. I called the lab, then I called Dr, Kwoks office. Her office contacted the lab on my behalf, because if the first sample could not be read, they should do the second one for no charge. The issue was resolved. Dr. Kwok has also done surgery on me, It resolved my issue. The only negative thing I have to say is that there was a wait for the visit. I am sure its because she her office was still working out kinks from her being in her own practice."
