We love to see you smile

Our goal is to contribute to our patients’ quality of life by providing the finest orthodontic care we can, in a loving and caring manner and in an atmosphere that is enjoyable and enriching to our patients and staff. We appreciate the trust you have placed in us and for the opportunity to care for you and your family. (Click here to see what patients and their families have to say about RTO.) We welcome you.

We specialize in both child and adult orthodontics, so it is not unusual to have parents and their children side by side; RTO is truly a family practice. Smiling Children We look forward to welcoming you to one of our four conveniently located offices: in Acton, Billerica, Lowell or Westford. You may enter a guest, but you will leave as family. We love what we do, and we love to see you smile.

Note: The Acton office will be undergoing renovations until November. Until then, all Acton patients will be seen in our Westford office.
