I first went to Dr. Calvert in the 80's for an emergency root canal of an abcessed tooth. My experience was absolutely the best I could have ever hoped for. The man is absolutely a genius. Flash forward to 2011, another emergency root canal. Same great service, unbelievable chairside manner, most caring staff. Did I mention Pain Free????? He took me late in the afternoon, did the procedure and finished a little before 7:00 PM. He cares. And If you have dental anxiety, don't waste your time looking for someone better. He's the best.
