Greg is a board-certified pathologist who is currently at Harvard on a dermatopathology fellowship. As a pathologist, he is an expert on health. He knows quite a lot about disease -- what causes it, what cures it, and what progress researchers are making to rid the world of it. Greg spent three years studying cancer at Duke University and has been published in a bunch of academic journals. Amy is the Director of Provider Relations for North American Health Care. Her doctorate is in communication, which means that she draws from the areas of psychology, sociology and the humanities to understand health from a holistic approach. Where Greg excels in health, Amy's focus is on wellness. Together, they work to uncover the many, many factors that help a person stay healthy, live longer, and have a better quality of life.
