I'm a member of a largely invisible workforce in the health care industry. I don't wear a uniform or commute to an impressive office in an elaborate medical complex. I don't have tenure or advanced degrees or a professional suffix after my name. And yet, despite a lack of any discernible professional recognition, or public awareness to speak of, I'm entrusted every day, to deliver some of the most intimate and important services to some of our nation's most vulnerable citizens.
