Ferdie Pacheco wasn't much of a doctor. Most doctors don't earn a living selling paintings, working as a cornerman and serving working for various television networks as a boxing commentator and matchmaker. Of all his "careers" as an adult, I think he was a physician in a poor section of Miami for couple years. What was his speciality in medicine? Does anyone know? Did anyone ever ask? All I've ever heard, in terms of medicine, is him prescribing medication and stitching fighters after matches. That's about it. Pretty rudimentary stuff.
