Your specialists in Invisalign, braces and surgical orthodontics in Newton and Worcester Massachusetts

Class One Orthodontic Associates has been providing quality orthodontic care in Newton and the Worcester area for over 30 years. Dr. Faeze Fadiani and Dr. Nayson Niaraki are a mother-son team who understand the needs and expectations of local families. We are dedicated to using the most advanced orthodontic technology in order to provide comfortable and accurate orthodontic treatments. We are happy to provide such services as braces, clear braces, Invisalign and so much more. 


We focus on people

All treatment plans are tailored to each patient's individual needs. Care and consideration are taken by our doctors and staff to treat each patient as an individual. We never take a “cookie-cutter” treatment approach where every patient receives the same treatment modality regardless of their chief reasons for seeking orthodontic care.



It's best for the orthodontist to see children by age 7 to advise if orthodontic treatment is required and it is the best time for that patient to be treated. Learn more about Early Treatment.



With Invisalign and Invisalign Teen, you can straighten your teeth without metal wires and brackets getting in the way.  Another option for teens who don't want metal braces. Learn more about Invisalign, Invisalign Teen, and why not all Invisalign providers are the same.





One of every five patients in orthodontic treatment is over 21.  We offer traditional metal braces, clear braces as well as Invisalign invisible braces. Learn more about braces.



Surgical orthodontics (also known as orthognathic surgery) corrects jaw irregularities to improve your ability to chew, speak, and breathe. Additionally, surgical orthodontics may be used to improve facial appearance. Learn more about surgical orthodontics.

What sets us apart

We understand your desire to seek the best possible orthodontic care for you or your child and to meet your expectations; we take your smile personally. This means that we treat each patient as a unique human being and we care about each individual. We also make sure that each patient is completely satisfied with the end result. To help us accomplish your desires, we exert our effort and passion in several different areas:

  • Your time is valuable, and we try to always keep all appointments on time using our highly efficient digital scheduling system

  • We offer state-of-the-art digital x-rays, thereby eliminating 90% of the exposure to radiation.  We are one of the few offices in the area to do this.

  • You will always receive an email/text message before your next appointment to keep you organized and on course to complete your treatment on time.

  • The benefit of having two orthodontic specialists in the office at the same time is tremendous. Although Drs. Niaraki and Fadiani have very similar treatment philosophies, the doctors routinely confer with each other to establish definitive treatment plans in their patients’ best interests.

  • We are up to date on the latest technology. Both doctors attend many hours of continuing education each year and continually incorporate the latest research into their treatment plans and philosophies.

  • We have years of experience. Dr. Faeze Fadiani established Class One Orthodontic Associates over thirty years ago. She is still here, along with her son. Drs. Niaraki and Fadiani are members of the following professional affiliations, which provide endless opportunities for continued education, and the ability to provide you with the most advanced treatment options available:
