Psychedelic Practitioner Training: Core

Fundamentals of psychedelic facilitation and care

First-hand experience with non-ordinary states of consciousness

Are you a practitioner looking to begin or expand your expertise in working with psychedelics? Starting in February 2026, our Core program offers a comprehensive, 
practice-driven immersion into the fundamentals of psychedelic facilitation.

Through two modules — an 18-week Education Module and a 4-day Experiential Retreat — you’ll be guided through the full arc of practice: from screening and preparation, to dosing-day facilitation, to post-journey integration. Along the way, you’ll work with therapeutic modalities such as Constellations (the ETI Method), Internal Family Systems (IFS), and trauma-informed approaches, while developing the ethical grounding and embodied confidence to practise with safety and integrity.

    Education & Intervision

    Our Education Module is more than just a standard foundation—it's a practical, hands-on foundation for therapists and other practitioners who want to learn how to actually do this work. While we cover essential topics like the history, neuroscience, and therapeutic potential of psychedelics, the real focus is on practical application. Through expert-led, interactive online sessions, you will gain real-world insights into dosing protocols, integration techniques, and the ethical considerations you may encounter in practice.

Our belief

The training for mental health practitioners is a combination of training in which therapists experience the transformative power of a high dose of psilocybin-containing truffles by themselves, and apply their insights to their own lives and their professional work with others.

We believe that experiencing a psychedelic session in a safe and supervised way is important to fully understand its magnitude. You will also experience being a psychedelic facilitator and what that entails, you will expand your knowledge about psychedelics and psychedelic-assisted therapy, and gain the skills to navigate the different levels of the unconscious

    Rogier
