“All 3 of my children have been to Class One Orthodontics and have had excellent results with their braces. I highly recommend Class One Orthodontics to anyone needing work done, you won't be disappointed”

Terri A

“Very pleasant and professional staff. I started my treatment and instantly felt comfortable to take my children for consult and starting treatment if needed. Their prices are a lot more reasonable than my general dentist.”

Jessica G

“4 years ago
Super fast, super friendly! I went to 6 other orthodontists for quotes prior to going to Class One. Not only did they quoted me the lowest price for Invisalign, but they are sure to give me the outcome I am looking for.”

Christopher M

“ Class One Orthodontics does a great job! They are very friendly and helpful. They went over everything with us about Christopher's treatment plan, helped us to work with the insurance company, and were even able to special order a spacer in a smaller size then they usually carry. Thanks for your great work! ”

Andrea

“ I would highly recommend Class One to anyone for any Orthodontic work! My daughter had her palet expander work done here 2 years ago, I had my braces done this past year (at 38 years old), and my daughter went last month for her braces as well. The staff is ALWAYS professional and pleasant. I have never waited longer than 5 minutes for an appointment. They are flexible with payment plans and extremely accommodating. You will not be disappointed in this office”

Karen D.

“ Both my Daughter and Son have had their orthodontic work done here and I have never had anything but a great experience. The staff have always been polite and very friendly. Also a big bonus is how they are almost always on time with the appointments....VERY PUNCTUAL. Great place to go for your orthodontic needs!!”

William B

“Our son’s journey with Class One Orthodontics has been truly remarkable! From the moment we stepped in with our son, we were met with friendly faces and a comforting environment. They patiently explained every aspect of his treatment plan, ensuring we were well-informed about each phase. They were also extremely supportive in handling our insurance matters. What stood out to us was their readiness to go the extra mile to order a smaller size spacer specifically for our son. We can’t express enough gratitude for their outstanding service!"

Nicole K

“ I had such a great experience with the doctor here. After not having a good one at a previous place, they transferred my Invisalign to this location and he took the time to be patient and help me with the process and making sure that everything fit and worked out. Their level of care and compassion and attention to detail is amazing and I can’t recommend them enough, this is a really great place to go to for Invisalign."

Nora A

“ I've always been self-conscious about my smile, so when I decided to finally take the plunge and get braces, I did extensive research to find the best orthodontist in town. Class One Orthodontics kept coming up with glowing recommendations, and now I understand why. Dr. Niaraki's comprehensive consultation made me feel informed and at ease"

Marcus F

“ Dr. Niaraki and the staff are an absolute gem. Their expertise and knowledge were evident from the very first consultation. I felt confident and well-informed throughout the entire process. My smile has been completely transformed, and I couldn't be happier with the outcome.  Class One and their team not only improved the alignment of my teeth but also enhanced my overall facial aesthetics.
I wholeheartedly recommend this orthodontist office to anyone. Trust me, you won't be disappointed!"

Emily J

“ Class one ortho provided an excellent Invisalign treatment experience for both of my two sons. My wife and I were really impressed with their expertise in Invisalign and the numerous benefits it offered.
From our initial consultation, Dr. Niaraki showed us how Invisalign worked and its advantages for kids. My sons did not want braces and they were able to go through their orthodontic treatment without feeling self-conscious."

William T

“ I started Invisalign treatment with Dr. Niaraki earlier this year after considering several other providers, and I am so glad that I chose Class One! Dr. Niaraki and his staff are extremely caring and professional, and I’ve been especially impressed by the clarity and detail with which Dr. Niaraki has answered my questions throughout the treatment process. It’s also been very easy to schedule appointments that accommodate my work schedule (and Class One has always been very flexible when I've needed to reschedule). "

Rebecca G

“ They are professional, kind, and always willing to go the extra mile. They took the time to explain our daughter’s treatment plan in detail, helped us navigate through the insurance process, and even managed to procure a smaller size spacer specifically for her. Thank you for your exceptional service!"

“ Dr. Nayson Niaraki and Dr. Faeze Fadiana have managed the orthodenture work for my four daughters and do an excellent job. In addition to being highly professional and experienced, they relate well to kids of all ages-elementary school kids to teenagers. They are thorough, explain everything well to patients and parents, coordinate well with clients' dentists, and truly care that all outcomes are perfect. The welcome at the office is super as well. I highly recommend this practice.
