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!
