Meet Dr. John J. DuPlessis, Jr.

Dr. John J. DuPlessis, Jr. has been practicing orthodontics since 1987. He was sure he wanted to be an orthodontist since seventh grade when he had braces himself. The thing he enjoys most about orthodontics is showing a patient their before and after photos, knowing he has made a positive change in their lives. Dr. D. enjoys working with children and adults, but has a special bond with younger patients. He is known as a magician and practical joker at times!

Dr. D attended the University of Kentucky for his undergraduate and dental school education where he earned his Doctor of Dental Medicine degree in 1985. He completed his Orthodontic Residency at Saint Louis University in 1987. He regularly attends continuing education courses, usually doubling the required number of hours.
