Dr. O’Reilly in her own words

"Having been born and raised in Ireland, orthodontics was not something that was too prevalent growing up, but became a field that fascinated me early on. Going through dental school, I realized it's the perfect blend of art and science as well as a field in which my patients would be my partners in treatment; becoming not just patients but friends. What other field allows one to build such strong relationships with one's clients? What other field brings such fulfillment and happiness to one’s work? I quickly understood orthodontics was to be, and did indeed become, my dream career. I learn something new every day from my patients, and I strive to make their visits the highlight of their day as well. I can't imagine any work more fun and rewarding than contributing to the health and wellbeing of our treasured patients. My goal every day is to not only make a difference in my patients' lives, but for them to know that we're giving them the utmost in specialty care. Orthodontics today is as much about providing my patients with a healthy, lasting, fully-functional bite as it is about creating an aesthetically-attractive smile."

Education and Experience

"I received my initial college and dental training from Trinity College, University of Dublin, in Ireland. I was certified in orthodontics at Eastman Dental Center in Rochester, New York, received an Master of Science in Oral Biology from the University of Rochester’s Graduate School of Medicine and Dentistry, and am a board certified Diplomate of the American Board of Orthodontics. My broad experience in the orthodontic field includes extensive treatment of young children, adolescents, adults, children with craniofacial anomalies and other specialized applications.
