I have been coming to Dr. Mullen since 1987. He and his staff have always been pleasant and professional - this may be the only dental office that patients look forward to visiting. In 17 years, I've never had a bad experience. The one time that I had an emergency he was willing to fit me in on short notice. How is his work? I'm 47 years old, I first saw him after several years of dental neglect, yet I still have all of my teeth and all are in good shape.
