Stan Grof, M.D., Ph.D. is a psychiatrist with more than fifty years experience researching the healing and transformative potential of non-ordinary states of consciousness extending the Western cartography of the psyche beyond biographical experiences to the perinatal and transpersonal realms. Founder and past President of the International Transpersonal Association (ITA) he together with Abraham Maslow and others formulated the basic principles of transpersonal psychology, a discipline that explores the full spectrum of human experience and attempts to integrate spirituality and new paradigm science.

Stan and his wife Christina Grof developed Holotropic Breathwork™ – a powerful tool for accessing those healing potentials of non-ordinary states of consciousness. Following this development Grof Transpersonal Training™ (GTT), an extensive training program for Holotropic Breathwork™ facilitators was created and is active worldwide (

The principles of Holotropic Breathwork™ can be found here.

Cary Sparks <p>Cary Sparks (director, teacher) co-directed Grof Transpersonal Training with her husband, Tav Sparks, until his death in August, 2020. For the two years before that, Cary and a circle of advisors have shepherded GTT and Holotropic Breathwork® forward following Tav’s retirement. As Covid-19 put a temporary hold on in-person Holotropic Breathwork®, they created a program of “virtual modules” that offer the didactic, experiential and community components of in-person modules until HB can be done safely again. They have also been inviting the community to Movie Yoga® Salons and other free events online.</p> <p>Cary began administrating the GTT, the only facilitator training program in Holotropic Breathwork®, in 1990, working at that time with Stanislav and Christina Grof. In 1998, the Grofs sold the training organization to Tav and Cary. Cary organized multiple large workshops, trainings, and other events – led by Stanislav Grof, Christina Grof, Tav Sparks, and others – for over 30 years.</p> <p>Cary began facilitating seekers on their inner journeys in 1986. She was certified in Holotropic Breathwork® in 1988, and has worked as a facilitator, workshop leader, and at training events. In 2019, Cary certified as facilitator of a SoulCollage®, a practice for accessing one’s intuition and creating an incredible deck of cards with deep personal meaning. Both practices have in common a profound respect for the healing impulse and empowerment of the individual.</p> <p>Cary’s book Incensed: The Novel, is a humorous take on the world of transformational workshops (not breathwork!). In addition to writing, her passions are equestrian sports, rock music, nature and her family and cats.<br></p>
