Psychedelic Practitioner Training: Core

The 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 and trauma-informed approaches, while developing the ethical grounding and embodied confidence to practise with safety and integrity.

Integrate psychedelics into your professional and personal life

Our programs are designed to provide a deep understanding of both the theoretical foundations and practical applications of psychedelic-assisted care. You’ll gain insights from expert instructors, participate in interactive online lectures and intervisions, and engage in immersive retreats to apply what you've learned. With a focus on holistic training, small group sizes, and opportunities for hands-on experience, this program offers a unique blend of knowledge and practice to equip you with the skills needed for professional growth in this emerging field.

Our approach

Program Overview

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.
Experiential Retreat

The Experiential Module is designed to immerse you in real-world applications of psychedelic-assisted therapy. Through hands-on experience in guided retreats, you will take on both participant and facilitator roles, deepening your understanding of therapeutic techniques, group dynamics, and integration practices. This module offers a unique opportunity to refine your skills in a supportive, experiential setting.
Certification

With the certification from ETI, you can integrate psychedelic-informed practices into your professional work as a wellness practitioner or clinician. This certification enhances your expertise and opens opportunities for specialised roles in the rapidly evolving field of integrative healthcare. This program is not a license or authorization to practice psychedelic-assisted therapy outside of current legal avenues.

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

Accreditations

The ETI Practitioner Training is the first program in the Netherlands to be accredited by FGzPT, NVP, and NVvP—three leading bodies in the field of psychology, psychotherapy, and psychiatry. This accreditation applies to our Education Module, which includes 18 in-depth online lectures and reflects the quality and relevance of our training. International participants may apply for recognition of these credits (CE/CPD) with their local professional bodies.

Opening Access: 5 Funded Places on Our 2026 Core Program

At ETI, we believe this work must be accessible and reflective of the diverse spectrum of people it is here to serve. If the field of psychedelic care is to grow with integrity, it cannot be shaped by a single voice or perspective. It needs practitioners from different backgrounds, experiences, and motivations — people who can meet others where they are.

Previous Participants

"The Experiential Training Institute offers an outstanding and deeply transformative training. I am still impressed by how beautifully the retreat and the entire learning journey were structured. The sense of safety, the grounded energy, the thoughtful pairing of participants, the thorough preparatory work on day one, the journey days, and the integration on day four; everything felt aligned. It all flowed so naturally because of the team’s exceptional preparation and presence. I truly felt seen, supported, and held."

Sylvia
"Absolutely fabulous. Last weekend I finished my educational and experiential programme for becoming a Psychedelic Assisted Therapist. And it was amazing. The retreat in which all former lectures got practiced and integrated became a solid base and a highly inspirational starting point for my own practice in the therapeutical work with psychedelics. I received some healing Iand supported healing. Hans and Jeanine's team is warm, professional and accessible. "

Michael
"A truly outstanding training, delivered by a deeply passionate and dedicated team with an incredible amount of knowledge and experience. During the 4-day retreat everything we had learned came together in a powerful way. I gained so much clarity on how to apply all of it therapeutically, and after the live days I’m convinced that the ETI method really deepens the journey and strengthens integration. In short, a wholehearted recommendation for anyone who wants to guide others at a top level."

Talien
"The experience touched my heart in a very deep way. Everything was crafted with such intention — the location, the pairings, the music, the tiny thoughtful details (even the water bottles!), the hugs, the wisdom, the logistics, the kindness. This team doesn’t just run retreats, they live the work. And you can feel it in everything that Jeanine, Hans, Stine, Fleur and Ross do, in front and behind the scenes."

Sarah
"Working with psychedelics is starting to find its way into mental healthcare settings, and that's a challenging task. It must be done with wisdom, attention, care, skill, and knowledge, so that the power and healing of psychedelics can flourish. Hans, Jeanine, Stine, Ross, and Fleur are wonderful examples of this with ETI."

Merijn
“Hans and Jeanine are such a dynamic team, with depths of knowledge and a passion for training. I learned so much about the medicine and myself. I think the way they set up the event was very thoughtful. I really appreciated the medicine followed by the breath-work.”

Hilary, Clinician, USA
“I immediately incorporated a number of techniques and practices from the training, and I feel that it greatly enhanced my skills. In addition, Jeanine and Hans are incredibly skilled at what they do, and the retreat centre is a lovely oasis just outside of Amsterdam.

Rae, Psychologist, USA
“This training was one of the most profound experiences of my life. It not only provided me with deep knowledge about working with psilocybin, but it also will make me a better practitioner overall. I also gained a community of professionals that I feel a deep connection with. I can’t recommend this training more."

M. Tockanan, licensed Clinical Psychologist, USA
"This experiential training was profound in so many ways. I experienced so much growth, both personally and professionally. Jeanine and Hans’ teachings were incredible. I felt safe and supported the entire time. I am leaving changed for the better. Thank you."

E. Hill, licensed Marriage and Family Therapist, USA
"Hans, Jeanine and Stine have everything to help you discover and learn. For me, their training provided space, comfort, safety and lots of energy based on their commitment! Hans has a very sharp ear when it comes to music, which made the musical support perfect in my opinion. Recommended!"

Jochem van der Willigen
"I found the training for mental health professionals A-MA-ZING! I grew as a professional and I benefited immensely in my personal life. If you are looking for a course where you learn to work with psychedelics with integrity and respect for the clients’ process, this is the real deal. Hans and Jeanine are rockstar angels!"

Femke
"I would really like to recommend the Experiential Training Institute to all professionals who are interested in Psychedelics Assisted Therapy. Hans and Jeanine are very much capable to introduce you to this expanding realm and in guiding your own journey. I had a really good time with the group and take this experience with me for the rest of my life!"

Rogier
"I am still, weeks later, very impressed by this training. With a great group, I have expanded my therapeutic skills, but in addition, there was so much room for personal development and growth, that it could certainly be called a kind of group therapy that we all went through together. "
