Since 1976, Leonard Orthodontics has provided the highest quality of orthodontic care in comfort and style. With three offices stretching north of Boston, you will be able to find a convenient location no matter where you live in the area. Dr. Thomas G. Leonard and Dr. Jeffrey L. Leonard are one of the very few father-and-son orthodontic teams in our area. Dr. Thomas Leonard founded our office in North Andover nearly 40 years ago with a commitment to providing extraordinary smiles for life. Both doctors live in the area and are very involved with the community. Together, our doctors have helped thousands of people achieve the most brilliant, healthiest smiles and cannot wait to do the same for you.
