Walking down memory lane by surfing Wikipedia on the weekend, I remembered Dr. Peter Kunter, a German goalkeeper from the 60s and 70s who until this day holds the distinction of being the only player on the roster of a professional German soccer team with a doctor title.
Dr. Kunter pursued his medical studies while playing soccer on the highest level. He eventually received his doctorate in dentistry and opened his own dental practice (among his first patients were his team mates). He ran the dental practice full time while he was concurrently pursuing his career as a professional soccer player.
I wonder if there are examples of other professional athletes who successfully worked in different jobs while they were still active professional athletes?
