Dr. Gelfarb is a nice old man but he has no clue as to my condition or diagnosis. My dentist had provided me the correct diagnosis to a skin condition that I had. I am very surprised that he is still working, I believe he must be 80 years old. His office is dark and dingy, looks like he hadn't renovated since 1970's. I don't even believe he has a receptionist, when I called to make an appt, he booked my appt and when I arrived for my appt, he was the only one there. I don't even see a computer in the office. I don't even think he sterilizes his instruments. He definitely should retire. I don't think he can keep any patients.
