good dermatologist

Alan Kling has the personality of a dead moth.

Dr. Frankel on 7th Avenue.
Very friendly and, I assume (hope!) thorough.

Third on Dr Frankel

I wrote previously about Dr. Tesser:

"Mark has been a friend and my family's dermatologist for quite a few years. He is thorough, careful, and very insightful and empathetic. He correctly diagnosed a very unusual, potentially serious illness in my then-nine year old child (after other doctors had failed to do so), and helped my wife and myself maintain our sanity until further blood test results came back and provided some comfort."

5th on Dr. Frankel.

I have recommended him on other threads when this subject came up.

The efifcient way his office is run is exceptional. When he is with you he is focused and if your situation is an easy fix then he will deal with it and in 6 minutes you will be on the street again. However, if the situation is complicated or demands more of his time to make you understand what the problem is and make you feeel emotionally o.k. he will spend the extra time.
