Founder of Circles of Air, Circles of Stone, Sparrow Hart undertook his first wilderness rite of passage in 1971, a 5-month solo pilgrimage in the Cascades and Canadian Rockies. Over the last 30 years he has practiced modern and indigenous therapeutic approaches and has apprenticed with a variety of native and non-native "medicine teachers" in the United States and Mexico.

In 1988 Sparrow completed training at the School of Lost Borders with Steven Foster and Meredith Little, authors of The Book of the Vision Quest, and since that time he has been leading vision quests each year in New England and the Southwest. He has also undertaken over 20 quests of his own.

He is a father, writer, creator of the Mythic Warrior training, founder of the annual Men's Wisdom Council, and a frequent workshop leader around the country. He is currently in the process of completing two books: one, a practical manual on the vision quest, and the other, "Letters from the River," a lyrical exploration into deep ecology and living beyond the boundaries of the self.

Although widely-read, and well-versed in mythology and the sacred traditions of the world, his work comes out of his own experience. His personal journey includes the twelve steps; a long apprenticeship in the Toltec and Castaneda tradition; dream exploration, psychodrama, inner child work, and a wide range of shamanic practices. He aspires to be simply a human being, a person of the earth, and has an unique ability to bring matters of the spirit into the present, to make the ancient teachings of the connectedness of all life relevant to our modern and personal worlds.
