Bill Plotkin is a depth psychologist, guide of wilderness rites, ecotherapist, author, and speaker. As the founder and president of Colorado’s Animas Valley Institute, he has, since 1981, led thousands of people through nature-based initiatory passages, including a contemporary, Western adaptation of the pan-cultural vision quest. Previously, he has been a research psychologist, professor of psychology, psychotherapist, rock musician, whitewater river guide, and mountain-bike racer. As a research psychologist in the 1970’s, he studied dreams and nonordinary states of consciousness achieved through meditation, biofeedback, and hypnosis. His doctorate in psychology is from the University of Colorado at Boulder. One day in 1979, while a psychology professor at SUNY-Albany, Bill made a solo winter ascent of an Adirondack mountain. On the summit, he experienced what Joseph Campbell called the “call to adventure,” a world-shifting moment that lead him to abandon academia in search of his true calling.
