I know dr. Liang for years. He can definitely do things others can't even think of doing. He is a very competent and skilled surgeon. Some patients want everything nicely done without any discomfort. To me, they are bunch of whiners. If you want things done right, then look for him. If you demanded low quality, don't look for him. I respect him as a friend and a professional. People should be grateful to be treated by him. His skill and knowledge are definitely beyond dentist I know.
