Robert W. Firestone, PhD, is a clinical psychologist and author whose principle focus has been the subject of resistance in psychotherapy and people's resistance to a better life in general. His comprehensive body of written work elucidates how the avoidance of the true nature of the human condition contributes to interpersonal pain and suffering as well as to the crisis of fellowship in which we, as a species, find ourselves. Dr. Firestone is the author of fifteen other books including Voice Therapy, Compassionate Child-Rearing, Fear of Intimacy, The Self Under Siege, The Ethics of Interpersonal Relationships, Beyond Death Anxiety, and The Enemy Within.

Dr. Firestone is the consulting theorist for The Glendon Association. His studies on negative thought processes and their associated affect have led to the development of Voice Therapy, a therapeutic methodology used to uncover and contend with aspects of self-destructive and self-limiting behaviors. The concept of the critical inner voice has been applied to empirical research, developing The Firestone Assessment of Self-destructive Thoughts (FAST) and The Firestone Assessment of Violent Thoughts (FAVT), scales that assess the potential for suicide and violence. Dr. Firestone has also produced 35 documentaries with The Glendon Association.
