Dr. DeRienzo has been my dentist for more than 7 years. He has done several crowns and implants as well as root canals. I have always been please with the care he has provide me. He even went above and beyond the call of duty one time on a snowy Saturday when his office was closed. He met me at the office to replace a temporary crown that had cracked and broken apart on me. The temporary crown was scheduled to be replaces with the permanent crown the following week. Now I was scheduled for a business trip that coming Monday and would not be able to wait until my return. So he came in on this very SNOWY Saturday morning to give me another temporary crown that could last until I returned from my business trip. I am pleased with the professionalism that he provide me in my time of need. Thank you and I am pleased to endorse you.
