I canceled a much needed shoulder replacement in order to have this emergency colonoscopy, and have not been given the results other than a few words as I was waking up. I don't believe what he said is accurate, there is no picture to show me, I've not been told this previously, I have not had this particular problem that I had the procedure for, he doesn't know what it is because I never had a chance to tell him and he will not talk to me - in his office or on the phone and I can't get in to see him for two months. It's been two weeks and I know nothing.

Dr Alan Wang is a Dr., who communicates with me & takes time to discuss issues, meds, etc. I have been under his care about 12-13 yrs.& feel very at ease & comfortable with him! I also have recommended him to some friends & family, he is OUTSTANDING!

Dr. Wang is amazing!!! He truly has saved my adult daughter who was misdiagnosed from a previous physician and my mother who needed urgent care. He has a wonderful bedside manner and cares about the wellbeing of his patients. I would definitely recommend him. Along with my daughter and mom, I now go to him and my sister.
