Sometimes, the actual writing seems simple when compared with the behind-the-scenes effort to produce a textbook. We thank the following people for their editorial and production assistance: Quincy McDonald, Publisher; George Lang, Director of Content Development; Nancy Peterson, Developmental Editor; Elizabeth Stepchin, Content Project Manager; Michael Kern, Editorial Associate; Bob Butler, Production Manager; and Carolyn O’Brien, Design & Illustrations Manager.
We would like to thank the many Ohio University, Boston University, and Old Dominion University students and clinicians who volunteered their time to serve as models for the third, fourth, and fifth editions.
