• Dr. Mannstadt is a terrific, terrific doctor. He listens and he doesn't rush you and he knows your history and there was one time when I was admitted, I was in the ER at MGHB and he came down and saw me. He took time out of his busy schedule to come see me and I've seen him on a regular basis and I can't recommend him highly enough. He is just fabulous.

• Dr. Mannstadt was thoughtful, thorough, and took the time to discuss my questions in detail. I appreciated that he explained his reasoning, acknowledged areas of uncertainty, and tailored his recommendations to my individual situation rather than giving generic advice. I left the appointment feeling that my concerns had been heard and addressed.
