Meet the Doctors


Suzanne Cirino Duvalsaint, DDS, MS


Dr. Duvalsaint specializes in Orthodontics and Dentofacial Orthopedics. She treats both children and adults, making orthodontics a true family affair.

As a mom of children ranging in age from middle school to college, she also brings a deep understanding of childhood and adolescent behavior and development which helps her to understand her patients well beyond their dental needs.

Dr. Duvalsaint is a graduate of Columbia University College of Dental Medicine and a member of OKU, the dental honor society. She was awarded the Alpha Omega award for the highest academic achievement in her class. Following dental school, Dr. Duvalsaint attended Rutgers University, where she received a certificate of orthodontics and a master’s degree in oral biology.

She continues to stay abreast of the latest research and integrates state-of-the-art technology into her practice.

Outside of the office, Dr. Duvalsaint is usually on the go! Along with her family, she enjoys hiking, running, cycling, skiing, and is determined to add swimming to that list.
