My mother had extractions performed by Dr. M. Elstein several times, and I had my third molars extracted by him without sedation when I was seventeen years old.
My mother has always been very pleased with his skills and demeanor. I remember my extraction being completely painless with little swelling afterward.
As a predoctoral dental student, I have asked him to provide me with extracted teeth for my endodontic laboratory projects, and he has always been happy to help me out.
My impression of Dr. Mark Elstein is that he is an all-around nice guy with excellent skills.
