Dr. Chu was highly recommended. In fact, he's written a book and he is faculty at the NYU dental school. Let me just say - he is either too good to do dental work, suffers from a form of alzheimer, on drugs, has a serious case of Attention Deficit Disorder, or I am crazy. But I doubt the last one is true because although I am very picky about my dentist, I have found many dentist to be good enough - even if they have some flaws.Dr. Chu is like one of those celeb professionals. He can't sit still very long - he's constantly distracted by "very important" business he has to attend to in his office. An appointment that was supposed to take two hours, took nearly twice that time, and when he "finished", his assistants had to clean up his mess in my unfinished dental treatment. Twice I had to return in agony because of something he neglected. I also did not appreciate that he would insult his female assistants in front of me, while "male bonding" with other males. After each visit, I said to myself he's having bad day, he's famous so he can't be that bad, but I should have trusted my instincts. If it weren't for his very helpful staff, his customer rating would have been the lowest.
