Doctor NYC Dr. Fathollahi

Dr. Fathollahi is very sweet and attentive, but is also meticulously careful. By this I mean that she takes every possible precaution; I always leave her office with several referrals in hand and, in the past, she’s been very thorough in investigating symptoms that other doctors NYC overlooked. That may have saved my life, in fact. It goes without saying, I’m very grateful to be her patient. -ZocDoc
