About Us

Our History

Leonard Orthodontics began when Dr. Thomas Leonard opened our North Andover location in 1974. Soon after, in 1976, the Amesbury location was opened. As our practices continued to grow, the father-son team became a reality when Dr. Jeffrey Leonard joined his father in 1998. Dr. Jeffrey Leonard took over the practice in 2008, and we built and opened our newest location in Andover, MA.

In an effort to provide a more pleasant patient experience with updated orthodontic technology, our North Andover office was expanded and completely renovated in 2011. All of our offices are in convenient locations with easy parking and access. We continue to serve our patients in Andover and North Andover with state-of-the-art technology, high-end equipment and beautifully decorated office space. Our Amesbury office will soon be undergoing renovations to meet the growing needs of our patients.

Our Mission

We treat every patient as if they were our own family. Our goal is to consistently provide exceptional comprehensive orthodontic care in a warm and caring environment, using the best materials, staffing, and equipment available. We are proud to have continued this mission for almost 40 years, creating generations of beautiful smiles.

Our team treats every patient with the highest level of compassion, respect and admiration. We aim to make each patient's office visit the greatest part of their day – with the goal of providing extraordinary results and amazing smiles. Our highly trained orthodontic team is committed to helping you achieve what you deserve - a healthy, beautiful smile that lasts a lifetime.
