WORST Dr. uncaring & cold. Lies to you. All he cares about is money & test that are in his best interest. When you or a family member are diagnosed with an illness all these Doctors see are dollar signs. This Dr especially. Your in a vulnerable position & want to believe what a Dr tells you and that they have your best interest. Not the case with Dr Posner. My family member was put through unnecessary test because of Dr Posner & his phoniness & lies & he’s got an attitude on top of everything. My family member went down hill from there & passed away. I don’t recommend Mt Sinai at all or Dr Posner. It’s just very upsetting how uncaring a Dr could be. I don’t know how this dr can live with himself.

Not a fan on his lack of bedside manner, his passive aggressive comments to the patient and the patient's family was little to be desired. The most insulting piece was the blatant disrespect towards the patient when the patient found out the tumor came back. The staff was curt and unhelpful, if they spent more time making the patient comfortable and less time being insensitive maybe this review wouldn't exist. Don't waste your time...go to sloan.

He is on the cutting edge of research in the field of head and neck cancer. At the same time, he is a warm and caring doctor who is genuinely interested in helping his patients cope with the problems caused by their cancers.
