Meet Mary..

the gentle, compassionate soul behind Myco-Vision,

Mary Casanave Sheridan is the founder and guiding force behind Myco-Vision, a practice rooted in a deep respect for the human spirit and the illuminating potential of psychedelics. Mary has over a decade of experience in holding space for and advising on journeys of healing and self-discovery, as well as 6 combined years of mentorship and training, and 25+ years of her own transformative journeys. She combines her experience, wisdom and compassion to curate personalized ceremonies that honor the unique path of each individual she works with.

Mary’s approach is deeply integrative: blending breath, sound, poetry, movement, philosophy, meditation, herbalism, energy work, brain science, and therapeutic somatic practices with a reverence for indigenous traditions and the spiritual dimensions of psychedelic healing. Her work is not simply about the psychedelic journey itself—it is about exploring the nuance and texture of the spirit and pushy in these realms, and weaving the lessons learned into the fabric of daily life, afterwards. Thus, fostering meaningful, lasting transformation at the personal and collective levels.

At the core of Mary’s practice lies a profound Spiritual conviction—a belief in cognitive liberty and the inalienable sacred right and responsibility of each individual to explore their own consciousness, authentic nature, and connection to Spirit. She approaches this work as more than a professional offering; it is her spiritual calling, a vocation rooted in truths that transcend the boundaries of conventional Western laws and wisdom. To Mary, traveling in the psychedelic realms is inherently a sacred act; one connected to ancestral practices and universal principles of growth, liberation, and connection.

This deeply held value guides her decision to remain outside Oregon’s licensed framework, as she chooses to honor the spiritual and transcendent nature of this work without compromise. Mary believes healing cannot be dictated or contained by rigid systems of control, and she is proud to offer a practice that stays authentic to these values, grounded in freedom, respect, and reverence for the sacred.

Beyond her work with individuals, Mary is a vital thread in the tapestry of the broader psychedelic community—an advocate, educator, and builder of spaces where dialogue, equity, and shared growth thrive. She heads a community for local medicine workers and space holders; providing educational opportunities, peer support, social events, and a mentorship program. She also contributes a monthly column to The Source Weekly, answering reader questions about psychedelics and platforming the voices of indigenous and marginalized communities. With an enduring commitment to safety, accessibility, and inclusion, she fosters spaces where people feel supported, seen, and included. Whether holding space for personal transformation or advocating for ethical, community-centered approaches to psychedelics, Mary’s work is a testament to her unwavering belief in the power of connection, authenticity, and the sacred right and responsibility we each have to explore the vast realms of Spirit, consciousness, and truth.
