Mark Coleman has been engaged in meditation practice since 1981, primarily within the Insight meditation tradition. He has been teaching meditation retreats since 1997. His teaching is also influenced by his studies with Advaita Vedanta and Tibetan teachers in Asia and the West, and through his teacher training with Jack Kornfield. Mark primarily teaches at Spirit Rock Meditation Center in California, though he also teaches nationally, in Europe and India.
He leads backpacking retreats, nature-based retreats, and teaches retreats for environmental activists in the wilderness at Vallecitos Mountain Refuge in New Mexico, and at Knoll Farm in Vermont. In the Bay Area, Mark has a counseling practice, where he integrates his studies of psychotherapy and meditative work. He is the author of “Awake in the Wild - Mindfulness in Nature as a path of Self-Discovery." Mark has been an avid hiker, and backpacker for most of his life and spends much of his time in the outdoors. He lives in the woods in Marin County, Northern California.
