When asked why she chose orthodontics as her profession, Dr. Prehn said: “Practicing orthodontics allows me to help people in many ways. Some people seeking treatment are unhappy with the position of their teeth and want to straighten them for aesthetic purposes. For these patients, giving them the smile of their dreams gives them self-confidence. Other people are looking to correct more serious problems that affect eating, speaking and tasks that help them function in life. Whether their problem is mild or severe, it is so rewarding to see patients walking out of the office feeling happy about their treatment.”

Dr. Prehn now lives in Wynnewood, PA with her husband, Joseph and her kitten, Maisie. When she isn’t working, you can usually find her outside running. Her other favorite pastimes include going to musical concerts, traveling, reading and spending time with friends and family. Dr. Prehn is a singer and plays the trombone and piano. In addition to her work in the office, Dr. Prehn volunteers her time at local health fairs, performing dental screenings and teaching people about keeping their teeth healthy.
