T. Sean Casey, M.S. is the founder and director of ANCESTRALCIRCLE.  Sean has journeyed around the world, visiting countries as diverse as India, Russia, Iceland and Tahiti, and into the Arctic Circle. His interest in Native American philosophy began when he was a boy, and starting in the 1970s Sean began to immerse himself in those teachings, legends and lore. As he went along he had the opportunity to receive his training in ceremony through close association with a great number of well respected American Indian elders. Foremost among them have been his “Spiritual Uncle” Gheezis Mockwa (a world visionary and medicine man from the Chippewa tradition). To fulfill a four year commitment, Sean danced in the Four Nation’s Sun Dance led by Charles Chips, and later by Milton Highbear.  For more than seven years he lived and traveled throughout Europe supporting people on Vision Quests and sharing his knowledge of Native American Philosophy and Ceremony.  While in Europe Sean was influenced and inspired by the work of English Druid, Phillip Carr-Gom and Hungarian Shaman, Josca Soos. He has also acquainted himself with some of the spiritual drumming practices of the Sami (Lapland) people of northern Sweden. Sean is a Ritual Elder and has knowledge of many traditional healing techniques. The ceremonies he currently teaches are not related to any American Indian tribal tradition. In recent years he has been actively working to revive the ancient Irish spirituality that is his genetic heritage, and through ANCESTRAL CIRCLE, works to encourage people of all cultural and ethnic backgrounds to rediscover the ancestral tribal links to Earth-Connected Spirituality that resonate in us all. Sean is a State Certified Clinical Hypnotherapist, and holds a Master of Science degree in Counseling Psychology from Dominican University. Sean has published two books of poetry, and is currently residing in San Francisco.
