Shinzen Young - Shinzen has been a significant Dharma and meditation teacher for me and the source of many of the teaching approaches I use. His Web site is a great resource.
Impermanent Sangha is the non-profit I run that sponsors Nature and Wilderness Retreatsin the mountains and rivers of Colorado and Utah.
Eric Kolvig - Eric is my other main teacher and mentor. He started teaching wilderness retreats in the early 90's, inspired and taught Impermanent Sangha retreats with me for years, and even came on a river retreat as a yogi. He is pretty much retired but if you can sit a retreat with him, do it.
Adyashanti - I regularly sit retreats with Adyashanti and he has become an important teacher for me. Adyashanti’s nondual teachings are similar to those of the early Zen masters and Advaita Vedanta sages, and express both the infinite possibilities and ordinary simplicity of a spiritually realized life. Adya teaches retreats and week end intensives worldwide, including in Boulder once a year.
Peter Williams - Peter is a fellow Boulder area Dharma teacher. He offers a weekly Thursday night sitting group, frequent short retreats in Boulder, and also teaches Impermanent Sangha retreats.
David Loy - David is another local Dharma teacher who has been working on discovering and clarifying the connections between awakening and social and environmental issues, and understanding how major challenges such as violence, inequality and climate change are at heart a spiritual crises/opportunity. He also teaches with Impermanent Sangha.
Zen with Len - Kensho Len Silverston is a Zen Meditation and Mindfulness teacher in Castle Rock who comes and leads a group in Boulder about once a month. He has great perspective and insight.
