Meet the Team

Instructors & Doctors

The best education comes from having the best teachers.

We know a thing or two about dentistry. The dental assisting school was founded by Cumberland Pediatric Dentistry and Orthodontics (CPDO), formed by a group of dentists with the mission to provide quality dental care. They, along with a several other general and pediatric dentists, come from all walks of life to bring you the best dental knowledge and discipline you’ll find in Tennessee.


However, being a great instructor comes with its own set of skills. Our teachers have worked and gathered experience from a variety of dental practices, and have trained and instructed many other dental assistants. They have trained some of the best in the field, and now they’re ready to teach you!
