Tim began his Buddhist studies in 1977 under the late Chögyam Trungpa Rinpoche in Boulder, Colorado. In 1981, Trungpa Rinpoche invited Mingyur Rinpoche’s father, Tulku Urgyen Rinpoche, to teach in Boulder. Profoundly moved by him, Tim and his family moved just a few months later to Kathmandu to study with Tulku Urgyen and his sons. During the twelve years that he lived in Nepal, Tim studied with many of the older teachers living there and worked as a psychotherapist serving the international community. In 2000, Tim moved to Cape Breton, Nova Scotia where he served for three years as the director of Gampo Abbey, the largest residential Buddhist monastery in North America. He is presently the president of the Pema Chödrön Foundation, which supports Gampo Abbey.
In 2003, after a visit by Mingyur Rinpoche to Gampo Abbey, Tim started the Yongey Foundation to support and promote Mingyur Rinpoche’s activities in the West. Tim lives with his wife Glenna in Steamboat Springs, Colorado, where he leads an active community that follows Mingyur Rinpoche’s teachings and those of his family lineage.
