When the series “Emergency” ended, Mantooth was asked to become a real paramedic. He had gone thru the actual training to make the show look reasonably real. All he needed was a refresher and the test. He decided to stay with acting.
I checked the IMDB and he had a pretty prolific career. Nothing like 6 years of a steady paycheck, but didn’t lack for work. Looks like he retired in 2010. I liked the show, it was pretty realistic.
When I watch Adam-12 reruns I think Malloy and Reed wouldn’t make it through a shift these days.
