Dr. O'brien's office is very welcoming. The staff is friendly and courteous. Nelly did an awesome job cleaning my stained teeth and making them look white without bleaching. Erica does a good job with schedules. Dr. O'brien is knowledgeable and great at what he does. He's been doing miracles on my teeth for years.

Excellent. Had my periodic teeth cleaning & exam. As always, couldn't be happier.

I can’t imagine a better dental office! I have been Dr. O’Brien’s patient for many, many years. I love his kind, gentle manner and his genuine concern for his patients. I love that his staff has always been equally warm and caring. I love that he and his staff volunteer their time each year to provide dental care to impoverished children in Guatemala. And I love, love, love that his son (Dr. Kevin) has joined his practice!
