  • Graduated from University of Tennessee Center for the Health Sciences College of Dentistry in Memphis, he continued his education at the University of Tennessee.

Dr. Sain’s Passion for Orthodontics and Community Involvement:

"I can't think of anything more enjoyable than seeing kids grow up and realize their potential. This is true whether it is helping them realize the best possible smile and facial appearance or being a part of their spiritual and physical development. The practice of orthodontics allows me to participate in what I love doing! What a blessing!"
