Dr. Camelia Shaheed earned a BA in Psychology, MA in Rehabilitation Counseling, and Ph.D. in Counselor Education and Supervision from the University of Arizona. At the University of Arizona, her primary research focus is the delivery of supervision, not surprising as a Licensed Professional Counselor with 30+ years of practice in Arizona as a psychotherapist, clinical supervisor, and administrator. Her areas of expertise - personality disorders and supervision delivery - have been the focus of many public and professional presentations. Furthermore, she "gives back" to the community with over three decades of pro bono support. Overall, those experiences inform the Essentials Series that begin with this book. Why write it? Beside the fact that graduate students need some texts to give them the basic facts, she considers this book essential. Graduate counselors must know how to read research. Otherwise, what are we doing? Too, she considers the Series integral to her most significant role -- that of instructor and mentor to future counselors and supervisors. In this way, she ensures the baton is worth passing before she passes it.
