By far, the best oral surgeon I’ve seen - over the years I’ve been to 2 others. I was also impressed with the facility.

There are no words for what an arrogant, rude, jerk this man is. He has no patience to calm fears, answer questions, or even act a bit caring.He is extremely untrustworthy. It's his way or the highway. And he will ruin your life while he's at it. Stay far away!!
