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. I am licensed to practice dentistry and orthodontics in Ireland, the United Kingdom, all member countries of the European Union, the District of Columbia, and Maryland.”

“In the free time afforded to me from empty nesting(!) I enjoy running, cycling, doing hot yoga, and kayaking. I love spending time with my three adult children. My son lives in New York City, and recently became engaged! My oldest daughter is currently attending Pepperdine University Law School. My youngest daughter is on her way to entering the orthodontic field! I am deeply proud of each of them.”

Absolutely wonderful experience from check-in to check-out. Professional, friendly, and courteous staff in a beautiful state-of-the-art facility. Dr. O'Reilly is extremely knowledgeable, thoughtful and did a remarkable job of not only providing me with a “this is your mouth 101” course, she also suggested several professional treatment recommendations. I can't speak highly enough of my visit, and I wouldn't hesitate to recommend her to anyone considering treatment options. You've been warned - expect an amazing experience!

I had been dealing with an issue of my bite being off for months and was extremely apprehensive about getting braces as an adult. Dr. O’Reilly and her outstanding staff immediately put me at ease. Her team and her not only made me feel comfortable about one day getting braces, Dr. O’Reilly took the extra time and care to discover an underlining condition in the root of my tooth which in my opinion went above and beyond the scope of care. Her team then took the time to get me an appointing with another specialist to solve the problem before I can get braces. Outstanding!
