Services
It is my obligation to provide care to you and your family, as though you are my family. I will want the best for your dental health, and will offer my opinion with honesty, transparency and compassion. I know that your trust and loyalty can only be earned through consistent performance and quality results.
I was fortunate to attend Wellesley College, where I double-majored in Biology and Art History. From there, I graduated from Tufts University School of Dental Medicine with my dental degree. I completed my orthodontic training and received my Master's in Medical Sciences at Harvard University's School of Dental Medicine.
The American Board of Orthodontics (ABO) was founded in 1929. It is the oldest and most prestigious specialty board in dentistry. The ABO's aim is to elevate the standards of the practice of orthodontia, to familiarize the public with its aim and ideals, and to protect the public against irresponsible and unqualified practitioners.

Thank you for choosing my office! I'm looking forward to meeting you and your family. It is my mission to provide you with the highest quality of orthodontic care in a considerate, personable, and comfortable atmosphere. During your first visit, complimentary digital images and a digital panoramic X-ray will be taken to offer the most comprehensive opinion.

Dr Diane and the entire staff at Amherst Ortho are welcoming, professional and straightforward. Dr Diane explained how much progress my child had made with just behavior cessation, and happily reported my child would NOT need braces. How often does a business NOT try to sell you something?

Our last visit to Amherst Orthodontics was great as always. We had to wait longer than usual (they are typically super fast and on time) but the friendliness and kindness pf the staff and Dr. Diane's amazing knowledge and ability to explain all processes in an easy way to understand, makes up for any wait. We as a family would recommend. 10/10

After being referred by a family friend (DMD), we had our very first consult for our daughter with Dr. Diane and saw Melynda and Morgan as well.
To say we were impressed would be an understatement. The cleanliness of the office was impeccable. The staff was warm and welcoming as soon as we arrived. My daughters consult was easy and painless with an extensive explanation at her level and mine of the future expectations of ortho care in the coming years. We left with a great understanding of what to expect as well as my daughters anxiety over the situation going from a 10+ to a 1, all thanks to

This office is top notch! I love how Dr. Dianne directs her conversation to the patient...even if the patient is a child! They should know what is happening in their mouth! Thank you Amherst orthodontics!

Dr. Diane and her staff are AWESOME! Great group and highly recommend if you need braces. Although no one looks forward to getting braces, the end results are worth the time and investment :) Thanks so all!!!!

Dr. Di and the staff provided my son with an AWESOME smile! The office was always professional, helpful and courteous--even though she is really busy. I think that's a good thing! Student pick-up bus is a definite plus for a busy family. Couldn't give a stronger recommendation. Amherst Ortho did not disappoint.
