Yeah, Dr. Carson has just been doing life and death kind of stuff. Nothing as big as creating a business.
(However, the docs I know, do have to be good business people in order to run their practices. Which are businesses...)
My wife is about to retire from a lifelong career running medical practices in every capacity, from front desk, coding, medical tech, billing manager and office manager. From her experience the waste in doctor’s offices is gut wrenching. No wonder doctor’s visits cost so much now compared to just 30 years ago.
