There's more on our future docs series, including a brief history of medical education in the U.S.here.
Dr. Phil Gruppuso started out as a pediatrician. He says that when he entered med school in the 1970s, his path looked really clear.
"It was pretty simple for me. I was able to complete medical school knowing that I would become a licensed physician and would practice medicine in a system that was not very different than the one I'd grown up in. And that was really true until about five to 10 years ago."
