    I am uniquely privileged to know Dr. Cornell as my trusted, expert Primary Care Provider. I was in the right place at the right time, when Dr. Cornell came to MGH, and I was able to select Dr. Cornell as my PCP. Dr. Cornell has expertly cared for me, since she came to MGH. Dr. Cornell is caring, thorough, and expert. She has an amazing knowledge and memory of my health conditions, and my quirks, as a patient. I can't think of any better PCP at MGH/MGB. Dr. Cornell is the consummate representative of medical experts at MGH, and Primary Care Physicians at MGH. MGH, and the Chairman of Medicine at MGH/HMS, should be very proud of Dr. Cornell.
