I first came to Dr. Kay in 1988, when I was 11 years old. I never forgot the good care I received in this office. When my daughter was 9 years old, we needed a place to take her for space issues (or lack thereof). I went to 3 different orthodontists in the area we live in, but I really wanted Dr. Kay’s opinion. After waiting a few months to get in, my daughter and I both felt good about the route he presented for her - it was very different than the other 3 options we had received. Though it’s over an hour drive, we find it worth it, knowing my daughter is getting the best care.

Dr. Morris & Dr. Kay are excellent! They really know what they’re doing and do what is best for the patient and their circumstances. I wouldn’t go to anyone else. They really do go out of their way to help you. Aside from that, they’re always very nice and friendly. Great to chat with 😊
