I went to Dr Janof only a couple of times but I did not feel comfortable because often he is the only one there and I think there is something wrong with a doctor being alone with a patient. He does have a receptionist/hygienist but she's not there all the time. I have never seen many patients (which makes me wonder about his practice) and the dentist talks way too much! I get the sense also that he wants to talk and not listen. Needless to say, I did not return. I recommend Dr Steven Salomon also on Ocean Ave in Brooklyn.
