If you want to be treated in an unprofessional way, go to see Dr. Lao. Not only does he avoid answering difficult questions, but his office staff and nurses are unprepared and rude.
I have been his patient for less than 5 months and I have already switched doctors. I have been so appalled by the things he and his staff do that I made a list of all the problems. I came up with ten MAJOR problems in the 3 visits I've been to.
Stay away from this office. Do not go or send your family members here. There are plenty of professionals in the Charleston area; find someone else.
And to any medical professionals reading this, please do not refer anyone to this office. It may be clean, but that's about the only good thing it has to offer.
