Very poor experience with Dr. Derienzo. While he worked on my teeth, he watched FOX news, constantly looking at the TV and not concentrating on my tooth. This resulted in major problems and I ended up going to another dentist that was able to correct Dr. Derienzo mistakes. I was in horrific pain for days, while he was on vacation. I went to his back up Dr. that could not figure out what was wrong, but charged me an emergency visit anyway. Please don't give Dr. Derienzo a chance to work in your mouth!!
