I've seen Dr Frankenberger about 4 times. Each time he was the same: he listens and is highly attentive, he cares about you, he's incredibly intelligent and explains everything else n a concise, clear manner. He could teach some of the other doctors a thing or two about how important compassion and calmness is to the patient. I read reviews a lot and many are off base. His reviews are accurate. He's an excellent doctor. He's also the best NYU has on West 52nd St.
