K “Mari” Castle, PhD, is a Holistic Health practitioner,  Life Coach, Grof® Holotropic Breathwork facilitator, Co-Director of Grof Studies and Author of two books.

Mari earned her PhD in Wisdom Studies through Ubiquity University in 2013, her Master degree in Transpersonal Psychology in 2008, and Oriental Medicine in 2004. She certified in Holotropic Breathwork in 2005, recertifying in Grof® Breathwork in 2023. She is passionate about facilitating people in holotropic states of consciousness and guiding a holistic mind, body, and spirit approach to health and wellness, one that includes an opening to their higher spiritual nature. Mari firmly believes that Breathwork can assist with awareness, expand our conscious Self, and realize freedom of life patterns. Mari’s PhD and books combine C.G. Jung’s perspective of Individuation with the ancient wisdom and mysteries of the 5,000 year old Sumerian culture. She traveled internationally and studied a number of cultural approaches to healing the body through a spiritual practice, including Buddhist, Sufi, Hindu, Pagan, Sumerian, and Eastern Medicine approaches. In her travels, she had a special opportunity to launch a Mindful Living project with Dr. Andrew Weil. She is an Author of two books combining modern and ancient wisdom to share keys for whole-life human development. Unveiling the Modern Goddess: through symbolism, chakras & myth and The Sacred Union: connecting the masculine and feminine within.

Sharing her knowledge of Holistic Health internationally has given Mari a deep understanding of culture. She recognizes the  impact of developing one’s personal or soul journey and is passionate about humankind reclaiming their connection to the sacred feminine and masculine within and  restoring our connection to nature. Nature is paramount to wholeness!
