The Team

Orthodontics requires the talent and assistance of many. We would like to thank the dental assistants, expanded function dental assistants, receptionists, and countless other health professionals who help us create a healthy smile at any age. While orthodontics promotes excellence in all aspects of dentistry, many other dental specialists play a vital role in supporting our efforts including general dentists, oral surgeons, periodontists, and endodontists.
