About Us

Our History

Leonard Orthodontics has been transforming smiles for over 50 years. Our journey began in 1974 when Dr. Thomas Leonard opened our North Andover location. Just two years later, in 1976, we expanded with a second location in Amesbury. The practice continued to grow, and in 1998, Dr. Jeffrey Leonard joined his father, creating a dynamic father-son team. In 2008, Dr. Jeffrey Leonard took the reins, and we opened our newest location in Andover, MA. Following the sudden loss of Dr. Jeffrey Leonard, his wife, Dr. Mary Angelic Gangoy has made a heartfelt commitment to carry on Dr. Jeffrey Leonard’s legacy and continue providing exceptional care to our patients.

As our practice continued to grow, we welcomed new orthodontists to the team, including Dr. Rachel Boschetti and Dr. Margaret Hostage. Their dedication and expertise add to the depth of care we offer to our patients.

To enhance the patient experience with the latest orthodontic technology, we expanded and completely renovated our North Andover office in 2011. All of our locations are in convenient areas with easy parking and accessibility. We proudly serve our patients in Andover and North Andover, offering state-of-the-art technology, top-quality equipment, and beautifully designed office spaces to ensure every visit is a positive one.
