Timelines come up often too, with multi-year braces and shorter aligner treatments finishing as projected or ahead of schedule.

My 9y/o daughter recently had an expander installed, and the process was so much less invasive than what we were told to expect at other orthodontic practices we consulted. We couldn't be happier with our experience! From our very first visit, Dr. Cos and his entire team have been wonderful. Everyone is incredibly friendly, welcoming, and always willing to help. Whether it's answering insurance questions, offering flexible scheduling, or simply providing excellent care in a clean and comfortable office, they've exceeded our expectations every step of the way. I highly recommend this office to anyone looking for an orthodontist!

I love the staff and the doctor as well, they are all so professional and very welcoming. I came back after many years and they are still the same kind team. I will be bringing my son soon for treatment. They work with you when it comes to scheduling appointments, payment arrangements and give you options for care. I’m glad they are still providing services.
