“I can't say enough about my family’s experience at this office. The orthodontists have great credentials and had the best interests of my daughter at the core of every decision they made. The costs were exactly what they said. Going to Lehnes Orthodontics made the entire process of braces much easier!”

“Dr. Lehnes and staff have been extremely wonderful to work with. While braces are not fun, the doctors and their staff have made it a pleasant experience. My daughter just had her braces removed and the staff threw a party for her! It just once again shows how great the staff is.”

“Dr. Lehnes has been so attentive to both my children with their braces. The entire staff worked well with the girls and made the experience as enjoyable as could be. My daughter just had her braces removed and said she would miss seeing the staff on a regular basis.”
