I was referred to Dr. Kallman from my regular dentist to correct a root canal gone bad. My experience with Dr. Kallman was such a good experience that I wanted to make sure everyone knew. I highly recommend Dr. Kallman, he's extremely understanding of anxiety and took extra measures to make sure my visit was a comfortable one. His office staff is also extremely pleasant and friendly. I could tell Dr. Kallman has been doing these procedures for years and years, he made the procedeure look effortless.
