What Our Patients Say

DR. PENG IS A MIRACLE WORKER! I'm 60 years old and because of my daughter's upcoming wedding I wanted to fix my teeth. I gave Dr. Peng literally 7 months to do what others considered to be an impossible mission and she delivered!
Emily N.
Dr. Peng is the best Orthodontist around - and I have three beautiful adult children to prove it! You get what you pay for and Dr. Peng is absolutely worth every penny and then some!

Shannon K.
They are so warm, friendly, and personable. The kind of place that remembers your name, even amongst their hundreds of patient faces to remember. They are not greedy and have your best and honest interests at heart.
