This book was conceived more than 5 years ago. Its production was a labor of love and a program of persistence. In our roles as educators of physician assistant students, we recognized that a textbook discussing ethics and professionalism focused specifically for PA students would be helpful to both them and their educators. Physician assistants are unique health-care professionals in many ways. During the beginning years of the profession, typical PA students had a significant amount of health-care experience; many of them were military corpsmen and medics. This experience allowed these early PAs the opportunity to see other health-care professionals in action and to appreciate not only.
