Dr. Duffy and his family then moved to Richmond, Virginia, where he completed his two-year orthodontic residency at the Virginia Commonwealth University at the Medical College of Virginia. In 2000, Dr. Duffy returned to his hometown to begin his private practice.

Kevin, Sam, Becca, Taylor

Though you will see Dr. Duffy at every one of your appointments, we assist him with many of the procedures during your orthodontic treatment, including taking a 3D scan, pictures, and/or an iTero scan, making impressions, securing your wires, making retainers, and, of course, helping you with the most important decision: what colors to choose. All of us encourage and teach good oral hygiene and will always be happy to answer any orthodontic questions you may have. As Becca, Taylor, Sam, or Kevin is working on your beautiful smile, be prepared to join in the conversation – no matter what tools are in your mouth, we can usually understand you!
