Kevan O'Neill, DDS, MDS


Kevan M. O'Neill DDS, MDS is a board-certified orthodontist who specializes in treatment of children with cleft and craniofacial issues at Dayton Children's Hospital. The Columbus native completed a prestigious fellowship in craniofacial orthodontics from New York University in 2013. Dr. O'Neill served as Associate Clinical Professor of Surgery for four years at Brown University in Providence, Rhode Island before returning to Ohio to become partners with his twin brother at Orthodontic Associates in Lima.

According to Dr. O'Neill's mom, he has always been obsessed with teeth. As a kid, he did not like the large gap between his upper front teeth. Braces treatment closed the space, which greatly boosted his self-esteem. He was so grateful that he decided he wanted to make a similar difference for others.

Dr. O'Neill was inspired to pursue a sub-specialty in craniofacial orthodontics during his residency training at the University of Tennessee. Dr. O'Neill willingly took on the more difficult cases and attended local cleft meetings in Memphis under the guidance of his mentor, Dr. Bill Parris. Another major influence on Dr. O'Neill is his dad, Dr. Jim O'Neill, a retired orthopedic surgeon who completed a spine fellowship at NYU when Dr. Kevan was only 5 years old. "When I had the opportunity to sub-specialize at the same institution as my dad, 25 years later, I knew it was the right decision!" Dr. O'Neill loves working with children. In his own words: "Kids are so much fun! They are honest to a fault, more resilient than most adults, and teach me new things every day."

Outside of work, Dr. O'Neill has a passion for outdoor activities, sports and the arts. When he's not in the office, you might find him sleeping in a tent along a long-distance hiking trail, playing golf with colleagues, or in front of the TV cheering on his beloved Notre Dame Fighting Irish. He is an avid foodie, film critic and Broadway aficionado.
