This is a slight adaptation of a post I recently made on my personal blog.
I've worked in healthcare technology for the bulk of my adult life; over a decade, in fact. However, I am not a clinically trained person. I can hold my own at dinner parties (I make a fantastic +1), can get through a demo with most doctors and hospital executives, but do not have any clinical training. I somehow manage to get through the bulk of my days knowing what I know.
