"Leiss has been amazing these past two years. The whole office runs like a well oiled machine and everything went smoothly with my daughter’s treatment, from the consultation, to making appointments, to getting her braces off! The staff could not be kinder or more helpful and my daughter loves Dr Leiss. We’re so happy with her smile and the care she received over the past two years!!"

Patient Reviews
“Leiss Orthodontics was wonderful! They transformed my daughter’s smile and gave her such confidence. My daughter had a very complex mouth and was in braces for a long time and they always took such good care of her. All of the staff are friendly and make you feel comfortable. We are going to miss seeing everyone now that my daughter is out of braces! We had a great experience and would recommend them to everyone!”
