Dr. Sarah Prehn

Dr. Reardon

“Practicing orthodontics allows me to help people in many ways. Some people seeking treatment are unhappy with the position of their teeth and want to straighten them for aesthetic purposes. For these patients, giving them the smile of their dreams gives them self-confidence. Other people are looking to correct more serious problems that affect eating, speaking, and tasks that help them function in life. Whether their problem is mild or severe, it is so rewarding to see patients walking out of the office feeling happy about their treatment. While I was growing up, my mother was a dental assistant. Frequent visits to her office allowed me to see what an amazing field dentistry is, and I knew from an early age that it was what I wanted to do professionally.”

    Love this dentist! Everyone is so nice and professional! I’ve been going here since for 24 years! They’ve always taken good care of me!

    Deb Y.12/28/2021

    I had pain in a tooth and called Wednesday morning and they told me to come right in. Dr. Reardon was very kind and thorough and explained my options. He ended up removing out an old filling and replacing it. His calm manner helped me through the drilling procedure and Sherry was great at replacing the filling. I appreciated that Dr Reardon fit me in to resolve the tooth pain. Excellent experience, even with the drilling part. Thank you! Thanks

    Got in quickly, Stephanie is kind and gentle. No pain. Dr. O’Brian very nice and also friendly. Overrall the office is clean and friendly and since I have to go to the dentist, I actually don’t mind this group.
