For him, some of the most rewarding moments of the job are when people come to him in severe pain, and he can immediately ease their discomfort. He also loves being able to transform patients’ smiles with temporary crowns in just twenty minutes. Their boost of self-confidence is nearly as rewarding for Dr. Greenstein as it is for the patients themselves. Dr. Greenstein attended the State University of New York at Stony Brook before attending dental school at the University of Medicine and Dentistry of New Jersey.
