Meet Mary:

A Guiding Light in the Psychedelic Realms

Mary Casanave Sheridan is the gentle yet fiercely devoted soul behind Myco-Vision—a vibrant sacred practice weaving ancient wisdom with modern approaches to healing and self-discovery. With over a decade of experience walking people through the entheogenic realms, six years of mentorship and training, and a lifetime of her own profound explorations, Mary has become a trusted guide for those seeking deeper connection, growth, and liberation.

Her work is both a craft and a calling, blending a wide array of practices—including mindfulness, sound, poetry, movement, visualization, herbalism, energy work, somatics, brain science, spiritual philosophy, and grounded presence.. Each ceremony curated by Mary is uniquely tailored to the individual, honoring their personal path while holding space for the mystical possibilities. For Mary, medicine work’s healing effects are not simply about the journey itself, but about its ripple effects—through bloodlines, communities, and daily life daily life, fostering personal and collective transformation. Deepening one's relationship to Self, Spirit, Earth, and the Great Mystery.

At the heart of Mary’s practice lies a profound spiritual conviction: the belief in cognitive liberty—the sacred right and responsibility we all share to explore our own consciousness and form our own divine connection. For Mary, this work is a deep spiritual vocation, guided by Universal and ancestral principles of responsibility, stewardship, connection, and freedom. She knows traveling in the psychedelic realms is a Sacred Act, one that transcends human constructs.

Mary’s impact extends beyond individual healing journeys. As an active voice in the psychedelic community, she fosters spaces where dialogue, equity, and shared growth flourish. She leads a community for local medicine workers and ceremony holders, offering mentorship, peer support, educational opportunities, and connection through social events. Mary also contributes a monthly column to The Source Weekly, where she answers reader questions about psychedelics and uplifts the voices of Indigenous and other chronically undervalued communities. It is this commitment to accessibility, safety, honoring, and inclusion that defines her work, ensuring every person feels seen, supported, and welcome in the spaces she creates.

Whether she is holding space for deep personal healing or championing ethical, community-centered practices, Mary’s work is a reflection of her unwavering belief in the power of connection, authenticity, and mysticism. She invites all who walk this path to embrace the beauty of their own becoming and to uncover the immense possibility that lies within the sacred—layer by layer, breath by breath.

With Mary, each journey is an invitation to awaken to the infinite, reconnect to Sacred, and dare to explore what is truly possible.
