I love Dr Carter, he tries to do right by his patients and to make sure you are happy with the service he provides. As for the tech I had today, I was not happy with the way she spoke to me. She was indirectly rude. She made it seems as if what I was explaining to her was not so because if I was doing my part then I would not be unhappy with the results thus far. To me it seems as if she was nicely telling me that I am lying about my invisalines and how I wear them. Was very displease with that portion of my appointment today.
