I HAD to review my dentist. He is the best. The office is clean, state of the art, he explains EVERYTHING in lay mans terms. Lets just say I moved to France almost 2 years ago and I still trust Dr. O’Brien and send my children to him for cleanings when we are in the US. Please see my nightmare review on Clinique Dentaire on Rue de France in Geneva, Switzerland for why you should go to Dr O’Brien if you live in NY. He is trustworthy and wont do anything that you dont need and wont lie to you about what is wrong. Ethics, number 1. When I am there for my appointment, I make my next one while I am there, they send reminders and all is well. I have sent him many recommendations and they all love him too. He will also take you in an emergency situation as well.
