WHY ORTHODONTICS
After 20 years in practice, Dr. Kastin still loves orthodontics! “When you work with patient’s month after month, you start to form a bond. The team and I start to look forward to seeing our patients as much as I like to think they look forward to their visits.” Helping change smiles while forming long lasting friendships with patients and families is what Dr. Kastin enjoys most about his profession. He also loves the art of orthodontics, as much as the science. He believes a smile is made up of a thousand little details and believes it is his job to make each one perfect
