R. O.

The staff took wonderful care of me from the moment I first walked into the office in Wheaton. Dr. Mark Kostko understood everything I wanted to do to improve my smile. The cosmetic dentistry that he provided looks great and my smile is incredible! I felt that they paid attention to all of my questions and I am very glad that I went to see him. I will continue to use this office and tell all of my friends about how pleased I am with them.
