Kendall was struggle with her nance appliance staying put. Many people would have automatically placed the blame on the 8 year old, but that was not the case. Dr. Eckels was very kind to her and apologetic that it took us so many trips to his office. He owned up to the improper fit and made it right. The appliance hasn't budged since. We have had nothing but a pleasurable experience there and Kendall always looks forwards to her appointments.
