Guided psychedelic sessions, truffle ceremonies, and retreats in the Netherlands

The Netherlands' most experienced psychedelic team 3500+ customers helped 300+ reviews 7 supervisors Nationwide network On-site support available

What we do

Our core activities consist of facilitating individual psychedelic sessions, truffle ceremonies, and multi-day retreats in the Netherlands. In doing so, we look not only at the session itself but at the entire process, ensuring the experience aligns as closely as possible with the individual, their needs, and the intended goal.

We start with an intake and preparation. During this, we focus on mindset, lifestyle, sleep, nutrition, intention, and the practical implementation of the session. Based on this, we determine which form of guidance, setting, and facilitator is the best fit.

During the session, we provide professional and personal guidance at one of our locations or at the client's location via our nationwide network. Afterwards, we also assist with integration, so that insights from the experience can better be applied to daily life.

Our mission

Triptherapie was founded to work on health, personal growth, and spirituality in multiple ways. The responsible use of psychedelics can contribute to this. It is our mission to integrate psychedelic sessions into various treatments aimed at different aspects of health, through a holistic approach.

If you are stuck after years of therapy(plant medicine and normal conventional DSM-5 professionals and therapist soldiers) and looking for stability, this is it. I think there is enough research out there that already tells that this is work heals, it could take time and maybe a lot of days you will think that you are moving backwards but that is never the case. It took me a year of visits and everytime I heal in 3 months what CBT did for me in 3 years. Ps except if you have strong addiction patterns or substance use then I can’t be confident now.

I’ve had the good fortune of attending TripTherapie on two separate occasions, about a year apart. The space itself is beautiful and thoughtfully designed, but what truly makes the experience exceptional is the quality of the therapists and people involved. I especially want to highlight Marcel. He brings a rare combination of balance, composure, experience, and relatability, even throughout complex emotional situations and group dynamics alongside the TripTherapie team. His presence creates a genuinely safe environment where people can explore deep layers of themselves while still feeling safe and supported. What stood out most to me was that the work did not feel abstract, it translated into meaningful insight and real world progress afterward. In this kind of work, experience and emotional steadiness matter enormously, and Marcel clearly has both. I’m deeply grateful for the care, professionalism, and integrity of the entire team.

I’m deeply grateful for the journey with Ronald. I felt safe and guided the whole time, which allowed me to open up to powerful symbols — from ancient masks to snakes and pictures that revealed something about my deepest fears, and that I could begin to relieve through what the mushrooms showed me and, of course, the integration work after with Ronald. Just a few days later I can already feel shifts in my clarity, softness, and connection. Truly transformative.

De afgelopen maanden heb ik twee sessies bij Triptherapie gevolgd; een individuele MDMA sessie en een truffelceremonie in een groep. Deze beide ervaringen zijn voor mij werkelijk life changing geweest en hebben mij enorm veel gebracht. Ik ben ontzettend tevreden over de professionele en warme begeleiding. Door de goede zorg en aandacht voelde ik me volledig veilig om de reis naar binnen aan te gaan en mezelf helemaal open te stellen. Daarbij is de loft een prachtige locatie. Ik ben Triptherapie heel dankbaar en kan het iedereen aanraden die op zoek is naar persoonlijke groei en heling.
