Patient Testimonials

julie a Home“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.” -Julie A. andrea Home“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” -Andrea
karen d Home“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!!” -Karen D. christopher m Home“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!” -Christopher M.
