Experience the unique potential of psychedelics

At the Experiential Training Institute, we offer psychedelic practitioner training programs and small group retreats for individuals and couples seeking to explore psychedelics in a safe and legal setting. Our psilocybin-containing truffle programs provide a powerful and transformative opportunity to delve into the psychedelic experience, deeply exploring mind, body, and spirit.

Psilocybin Retreats

Transformative, expertly guided retreats designed to support deep insight, healing, and personal growth.

Curious about exploring your inner world in a way that feels supported, grounded, and relational?
Our 3-day small group retreats are the foundation of our work at Experiential Training Institute.
Held in groups of up to 8 participants, these retreats offer a carefully facilitated space to explore consciousness, meaning, and personal growth — not in isolation, but in the steady presence of others doing their own work. This shared container supports safety, integration, and a pace that allows insights to unfold without pressure or performance.
All retreats are medically supervised, legally held, and delivered to the highest professional standards.
- Small groups (maximum 8 participants)
- Relational, carefully held container
- Professional facilitation and medical supervision
A more tailored, one-to-one container for specific needs and circumstances.
Private journeys are offered as a focused, individual option when there is a clear reason to work one-to-one.
These programs provide full discretion and dedicated facilitator attention, and are most suitable when particular therapeutic needs, life circumstances, or previous work indicate that a private container is the most supportive way forward at this stage.
Private journeys are not designed to be more intensive or “deeper” than group retreats — but different in how the work is held, and in what they ask of the individual.
Revised bullets
- One-to-one setting with full discretion
- Individually tailored facilitation
- Explored through a careful screening process
Seeking to reconnect, deepen intimacy, or explore your relationship in a more intentional and supported way?
Our couples journeys offer a carefully facilitated, private container for partners who want to explore their relationship with greater presence, honesty, and care.
These personalised retreats combine psychological insight with the ceremonial use of psilocybin-containing truffles, creating space to slow down, soften habitual patterns, and listen more deeply — to yourself, to each other, and to what may be asking for attention within the relationship.
Rather than aiming to “fix” or resolve everything at once, the focus is on creating the right conditions for understanding, empathy, and reconnection to emerge in a way that feels grounded and respectful for both partners.
What this might support:
- More open and attuned communication
- Increased empathy and mutual understanding
- Space to explore past experiences or relational patterns with care
- A renewed sense of connection and intimacy, at your own pace

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 practitioners who want to deepen their understanding of psychedelic-assisted facilitation through the unique lens of ETI’s approach: being in relation.
Across the program, we will move beyond the foundations into a nuanced exploration of what it means to be in relationship — with yourself, with others, and with something larger than yourself. This framework (intrapersonal, interpersonal, transpersonal) provides a rich map for understanding the layers of connection that can arise within psychedelic-assisted care.
Through a combination of lectures, and intervision groups, and live case discussions, you will build the sensitivity, presence, and capacity required to meet the complexity of this work.
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 ethical environment, providing the optimal conditions to discover new perspectives and meaning.
