"I was extremely happy working with Dr Alder and his staff while I had my Invisalign procedure done. I had metal braces twice before I tried Invisalign. After the metal braces were removed, my teeth began to move. That is when I decided to try Invisalign. The process went quickly and the results have been very positive. I highly recommend Dr Alder and Invisalign braces."
