Advanced Certificate in Psilocybin-Assisted Therapy

Train as a Psilocybin-Assisted Therapy Provider With a 5-Day Personal Immersion Experience in the Netherlands

Prerequisite: Current Participant or Alumni of the IPI Psychedelic-Assisted Therapy Training

Dates: November 7-11, 2022

As you may know, Psilocybin is currently in phase 2 trials with the FDA. If all goes well, we could see access to psilocybin therapy across the United States within a handful of years. In fact, Oregon voters have already approved Ballot Measure 109 which will make it the first state to legalize psilocybin services in a non-medical model as early as January 1, 2023.

Training with psilocybin is not only advantageous for working with this medicine directly; it’s also an amazing way to sharpen your skills as a psychedelic therapist with Ketamine, and other medicines as they become legalized. 

And, what better way to train than to get first-hand experience with psilocybin in a breath-taking destination near the Netherlands capital of Amsterdam? We’ve put together this exclusive retreat to allow you to do just that.

What to Expect

Since psilocybin is not yet practiced legally as a medical treatment outside of research, you will learn the safe use of psilocybin therapy within a non-medical application.

We care about your well-being and want to ensure that you have a meaningful experience. We placed a lot of attention on ensuring the retreat feels safe, secure, and is in a supportive environment.  We are here for you every step of the way – from preparation to integration.

Here’s an overview of what you can expect:


To help you prepare for the retreat you will receive documents from IPI explaining the risks, contraindications, and expectations of Psilocybin. You will receive additional documents including a truffle dosing questionnaire, dietary advice, intention setting, etc. for you to review. Two weeks prior to the retreat, you will participate in a 90-minute online group preparation session. On day 1 of the retreat you will participate in an in-person preparation session.


There will be two 6-hour dosing sessions throughout the week. You will have the opportunity to have a personal dosing session, as well as act as a co-facilitator for your colleagues’ session. The experience will be led by a psychologist, psychiatrist, and a teaching assistant. They will act as primary facilitators for the sessions so that you can relax and witness when you are acting as a co-facilitator and not receiving your dose.


Once your psychedelic journey is complete, we’ll help you to unpack your experience and learn how you can use the insight you gained from the session in your day-to-day life. To do this you will participate in an in-person integration group therapy, including art therapy, during the retreat. After the retreat comes to an end you will also participate in an online, 90-minute group integration.

A shuttle will be provided on the morning of November 7th from Amsterdam Rai Conference Centre to the retreat location in Culemborg. While there are ample hotel options near the shuttle pick-up location for the previous night, here are a few we recommend: 

You must arrive in the Netherlands 24-48 hours prior to the start of the retreat. This will ensure that you will make the shuttle, are well rested and able to get the most out of the experience.

Hans van Wechem

Hans van Wechem has almost 30 years of experience in psychiatry and started his career as a registered couples and family therapist before specializing in (group) psychotherapy of patients with early childhood trauma and attachment disorders.

He now contributes to projects such as MAPS in their efforts to investigate MDMA for the treatment of PTSD and has a wide network in the psychedelic community.

Marieke and her partner Erik are the owners of the fruit orchard where they created a ceremonial space for psychedelic retreats. Marieke specializes in personal leadership.

Marieke completed the full Psychedelic Practitioner training at Synthesis. She creates a calm atmosphere and a safe environment that makes it easier to let go of control, lower the fences and explore the areas of growth and potential possibilities. She does this in a soft, loving, curious and inviting way. Her central concepts are trust, love, attention, growth and authenticity.

What Happens After the Retreat?

It has often been argued that therapists are more effective in conducting psychedelic-assisted treatments if they have personal experience with psychedelics. Personal experience could enhance understanding, particularly in working with clients to make sense of experiences very different from what most people experience normally. 

As a participant in this retreat you’ll be able to use your personal psychedelic experience as a catalyst for therapeutic efficacy. 

Those who attend the retreat and complete the program will receive an Advanced Certificate in Psilocybin-Assisted Therapy.

Plus, you’ll leave with the following skills and first-hand knowledge: 

  • The importance and delicacy of therapeutic touch
  • How to embrace vulnerability
  • How our sense of self is constructed
  • How to deal with challenging emotions
  • How psychedelic therapy differs from traditional therapies
  • How to go about increased intimacy between client and therapist
  • How to use your psilocybin experience as a resource
