VERY TERRIBLE! Do not go here if you value your smile. Most of the workers here are constantly busy and don't take time to really look into what you need. Dr. Chen will just smile at you and say thank you see you next time! I was crying in their office because my teeth look so bad after paying thousands of dollars. None of them had the decency to get me even a piece of tissue paper. I think they just care about the money. Once I paid, they were done with me. My smile is ruined forever because the pieces chipped away can never grow back. NEVER AGAIN.
