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. Recently, with the sudden loss of Dr. Jeffrey Leonard, his wife who is also an orthodontist, Dr. Mary Angelic Gangoy has made a commitmentto our patients tocontinue Dr. Jeffrey Leonard's legacy.

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.

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.

Mary Angelic Gangoy, DMD is a native 'New Yorker who attended the State University of New York at Albany where she earned a Bachelor of Science degree. She graduated with honors from Tufts Dental School and earned her Doctorate of Dental Medicine before entering her TUSDM Orthodontic Residency, where she earned a Certificate in the Specialty of Orthodontics and Dentofacial Orthopedics.

During her educational years at Tufts, Dr. Gangoy participated in the university's research program at which time she became affiliated with the Robert Andrews Honor Society and International Association of Dental Research. Upon entering her orthodontic residency, Dr. Gangoy was inducted into Omicron Kappa Upsilon, the international dental honor society, and awarded the Furman - Rosenberg Scholarship for achieving both clinical and academic excellence.

Dr. Gangoy has served as a representative for her local dental society on the Council on Access Prevention & Inter-professional Relations and has served on the Wakefield Rotary's Board of Directors and co-chaired the organization's 20th annual 6K road race.

As a clinician, Dr. Gangoy gains professional satisfaction through providing treatments for children and teens, which positively impacts their course of growth and development. In mastering her skills with more aesthetic orthodontic techniques (such as 3M iBraces and Invisalign), she has developed a niche among adult patients seeking orthodontic treatment. When discussing treatment options with them, Dr. Gangoy places high value on aesthetic considerations and addressing their chief concerns for seeking treatment.

When not in the office, she and her husband enjoy family activities such as coaching (or rooting from the side lines) soccer and hockey games for their two sons. 'Dr. G. has a love and affinity for interior design and contemporary art work. She is a true admirer of fashion and enjoys staying physically fit by running and attending spin classes.

I love being an orthodontist. Over the years, I have had the opportunity to meet so many wonderful people, and the friendships that Ive built with my patients and their families are one in a million. It has always been my focus to make each patient feel at-home when they come to me for treatment and I work hard to give my patients the attention they deserve.

My education in dentistry and orthodontics has provided me with a strong foundation of knowledge and experience. Now, by regularly participating in continuing education, I am able to stay current on the latest technology and orthodontic treatments. My patients deserve the best, and continuing education allows me to provide them with more options and better results. I am a member of several professional associations that provide me with opportunities for continuing education.

I am truly blessed to live and work in such a wonderful community. I enjoy getting to know my patients and their families, and it is always such an honor to know that I have made a difference in so many of my patients lives. I couldnt ask for a better job or for better people sharing their smiles with me. I look forward to working with you.
