It provides the reader with an introduction to the people, events and activities that have shaped the growth of the profession from concept to reality. With the exception of the precedent years that date back to 1650, the Timeline presents a decade by decade progression in the use of non-physicians to provide health care in the United States and other countries. Embedded in the Timeline are links to other relevant sites, illustrations and references to enrich the reader’s depth of knowledge about our professional history and how it is intertwined with that of other health professions.
