I loved going to Schmidtke Orthodontics as a child. Now I am bringing my daughter and find it’s still the same great practice. Thank you for providing beautiful smiles for my daughter and I. – Andrea T.
My child had a difficult case. Dr. Schmidtke was sensitive to our concerns and went out of his way to make sure we felt comfortable with the care. – Robert F.
I decided to pursue orthodontics as a 43 year old woman. I admit, at first I wasn’t thrilled with the idea of wearing braces as an adult. The staff at Schmidtke Orthodontics quickly put me at ease with the decision I had made. They took the time at every appointment to explain exactly what was going to be happening. The time flew by and I am so happy I went through with it. My smile looks great and I feel much more confident. – Susan V.
If you’re looking for a top-quality orthodontic experience, I highly recommend Schmidtke Orthodontics. Dr. Schmidtke and his staff are second-to-none. They will have you smiling beautifully, and the friendships you’ll make along the way are truly priceless. – Deb S.
