I highly recommend Dr Alan Greenberg to anyone seeking the assistance of a person as opposed to a machine. In August of 2017, I went to Dr Greenberg seeking treatment for issues with my skin. I was pleased to be treated to questions and reciprocation on the part of Greenberg, as opposed to having someone stand on their soapbox and pontificate (the latter seems to be true of too many in the medical community, these days).
Just as well, even when I was not slotted for an appointment with him, I found it most easy to communicate via email and by phone. My issues with my skin have since improved greatly.
Without getting to be verbose, I would just like to stress that Dr Greenberg takes his patients seriously, always does the right thing by them, and doesn't charge out the wazoo.
