The Smile Dr. - We make our patient's smile

If you’d like to share some kind words and smiles, please ask our front desk staff for a comment card at your next appointment. We’d love to hear about your experience!


"Currently I have 3 children in braces. The best thing about going to Dr. K is that he treats each child individually. He looks at more than just teeth – focusing treatment on what will be the best for face and the jaws as well. Appointments are prompt and Tracey is always quick with a smile!"

                                                                                                   - Karen Ford (KF)


"I originally came to Dr. Kosiorek at the recommendation of my family dentist and also because of the close proximity of his office to my home and the children’s school. That was more than 10 years ago with my son Brian. When I look at his beautiful smile, it is easy to see why I came back with my daughter Kasey and now my son Daniel. But it’s more than that. Walking into the office is like dropping in on friends."

"We love Dr. K and Tracey too! I recommend them to everyone. The office is clean and inviting. Dr. K is always available day and night. He and his staff go out of their way to make the experience of braces as easy as possible. And Dr. K always takes the time to explain everything."

"From our first visit my daughter and I were made to feel right at home. The entire staff is always smiling and you’re treated like you’re part of the family. I wouldn’t want to be in any other office. Dr. K personally takes the time to explain what was accomplished at each visit. And Tracey is always cheerful and goes out of her way to accommodate our busy schedule. We actually look forward to coming to the office."
