To be recognized as the leading Orthodontic Practice of Western New York with an emphasis on Early Treatment.


To be the orthodontic practice of choice, utilizing cutting-edge technology in providing excellence in diagnosis and treatment planning.


Our Buffalo orthodontists believe that a beautiful, healthy smile is an asset to any patient. This is because a beautiful smile helps promote self-esteem, self-confidence and self-image. Orthodontic treatment brings the face, lips and teeth into proper proportion, as well as correcting problems with the occlusion (the way the teeth come together when the jaws close). Well-aligned teeth are easier to clean, creating better overall oral hygiene, thereby increasing the chances that your beautiful smile will last a lifetime. Furthermore, studies have shown that a healthier mouth can lead to a healthier YOU!

Early orthodontic treatment has its advantages, as well. Managing dental/facial growth and development leads to a nicer-looking, more individualized orthodontic result. We are also better able to identify contributing factors to poor dental/facial growth and development. If left untreated, these can contribute to relapse after treatment. In fact, we prefer to be interceptive and proactive in our approach to orthodontics, rather than taking the traditional reactive approach.
