I am celebrating the completion of my "Invisalign" treatment! I want to give a HUGE shout out to Dr. O'Brien, for her careful, gentle care during the past two years! Although I have been a patient of hers for over 15 years and have always been pleased with my quarterly visits to her office, I can't express my gratitude for my care these past two years! I am so appreciative of Dr. O'Brien's attention to details, and my final results. I am literally smiling ear to ear! I also want to point out that Dr. O'Brien is awesome when it comes to emergency treatment. I cracked my back molar while I was at work... Oh, it HURT so much! I called Dr. O'Brien 's office, and she quickly fit me in to see her by skipping her lunch break. Dr. O'Brien quickly assessed I needed specialized care, so she quickly contacted a highly regarded endodontist, and explained my problem. The periodontist performed an emergency root canal on me that very afternoon. I felt so fortunate that Dr. O'Brien has such strong professional connections willing to attend to her patient's needs. If you are looking for a quiet, gentle, professional, Dr. O'Brien is the best!
