This is an 80-minute session that presents mentoring, and how it relates to clinical supervision, professional practice and professional development. The primary format is a collection of video interviews, with several behavior analysts from across the country. Portions of the presentation were initially presented in the Primary Authors Presidential Address at the Florida Association for Behavior Analysis in September, 2007. Interviewees include Murray Sidman, Nate Azrin, Tim Vollmer, Richard Foxx, Mark Koorland, Julie Vargas, Hank Pennypacker, Jack Michael, and others, as well as the secondary authors. Interviewees were asked: Who were your mentors when you started out?, Who were your mentors/peers as you became established in behavior analysis?, and What persons or projects are you most proud of in which you had a mentoring-type role? These themes are used to emphasize the importance of having mentors and clinical peers throughout ones career, why peer review is so important to practitioners and their consumers, as well as showing the interconnectedness of all behavior analysts and how we all must support and strengthen our least-proficient practitioners to strengthen our profession.
