Dr. Diane Piccioni
Dr. Diane Piccioni grew up in upstate New York and moved to South Carolina in the summer of 2018 to begin her orthodontic career. She attended dental school at SUNY at Buffalo and completed her orthodontic training in New York City. Her hospital-based residency program afforded her the opportunity to treat several complex multidisciplinary and orthognathic cases over the course of three years. She focuses on proper diagnosis and meticulous treatment planning prior to beginning treatment in order to achieve the best outcomes possible.
In her spare time, Diane enjoys running, hiking, reading, traveling, and playing guitar. She is an avid sports fan, rooting for the Buffalo Bills, the Philadelphia Phillies, and the Syracuse Orange basketball team.
