Practitioner Training

Comprehensive, experiential training for those seeking to facilitate safe and effective psychedelic care.

Our Core Program offers a comprehensive and practice-driven immersion into the principles and process of psychedelic-assisted care. It’s designed for clinicians, therapists, and practitioners who are ready to begin supporting others in altered states — whether you're transitioning from adjacent fields, deepening your understanding, or bringing personal experience into professional practice.
Across the training, we cover the full arc of psychedelic work: from screening and preparation, through therapeutic modalities like IFS and constellations (ETI-method), to dosing-day guidance and post-journey integration. You'll also explore areas such as microdosing protocols, practitioner ethics, and how to build a sustainable practice.
Learning is grounded in real-world scenarios, role-play, and facilitated intervision groups — designed to equip you with not just the theory, but the embodied confidence and applied tools to do this work with skill, intuition, and integrity.
Our Advanced Program is designed for experienced practitioners already working with, or deeply familiar with, altered states of consciousness — whether through formal facilitation or extensive personal practice. This small, intimate cohort will explore complex case material drawn from the real-world use of psilocybin, supporting clients through a range of life experiences including depression, end-of-life anxiety, PTSD, grief, addiction, attachment disorders, chronic pain, and relational dynamics.
Expect rich case-based learning, in-depth psychological formulation, and expanded frameworks for working with meaning, emotion, and identity in the psychedelic space. We’ll also explore tools for measuring progress and assessing impact — such as the Schema Mode Inventory — helping you deepen your practice and bring greater rigour to your work in this evolving field.
Alongside the chosen Education Module, all participants will take part in a dedicated Experiential Retreat — an immersive, hands-on training designed to ground your learning in lived practice.
Held as a retreat in the Netherlands, this module offers a rare opportunity to step into both the participant and facilitator roles within a safe, expertly held setting. You’ll deepen your understanding of altered states through direct experience, while refining your skills in therapeutic presence, group dynamics, and integration.
What to expect:
- Embodied learning through real-world facilitation — guided by experienced trainers
- Alternating roles of participant and space-holder — offering a dual perspective on the process
- A focus on therapeutic techniques, ritual structure, and responsive support
- A small group format to allow for depth, safety, and shared reflection
We will be running several experiential retreats throughout 2026. Each retreat will provide the same high-quality, in-person training experience, with multiple date options to accommodate different schedules.

Where science meets ancient wisdom

We’re committed to facilitating psychedelic experiences which respect ancient traditions while bridging the gap with western psychology. Through our carefully designed, and evolving, programs we guide our clients through preparation, exploration, and integration within a safe and ethnical environment, providing the optimal conditions to discover new perspectives and meaning.
