The smiles behind your smiles.

Our Mission

Since 1927, our mission has been to provide an uncompromising commitment to excellent orthodontics in a caring and fun environment. OAG is a family-oriented practice that treats children, teens, and adults with intro-oral appliances, traditional braces and clear aligners. We are thrilled to get to know patients and their families. We strive for lasting relationships, often treating patients’ children and even grandchildren.
