What patients are saying about Dr. Callender



  • We have used Dr. Callender for both of our kids, one still in braces. We have nothing but great things to say about the work he and his staff have done…I would recommend him to anyone.

    -Nathan H.
  • As an adult, I wasn’t sure what getting braces would be like. Dr. Callender took the time to explain the process, what it would require of me, and even was up front about the risks of getting braces as an adult versus if I had done them in my childhood.
    I highly recommend Dr. Callender to any one thinking of getting braces as an adult or to anyone thinking of taking their children in for braces! Excellent customer service!

  • Both of my daughters were patients of Dr. Callender. They both could be models for Colgate after their wonderful results.
    I didn’t have braces as a child, but as an adult my front lower teeth began moving and were crowded and crooked. I, too, decided to go to Dr. Callender, and he used the Invisalign method for me.
    I couldn’t be happier with the results! Five out of Five Stars from our family.
