A personal and professional approach to psychedelic sessions
At Triptherapie, we have been guiding people through profound psychedelic experiences since 2018, looking not only at the session itself but at the entire process surrounding it. From our perspective, it revolves around preparation, guidance, and integration, ensuring that insights do not remain fleeting but truly have an impact on daily life.
What sets us apart is that we always provide tailor-made solutions. Not a standard program, but an approach that aligns with your background, intentions, and personal situation. Whether you come alone, with someone, or participate in a group, we ensure the setting and guidance are right.
If you would like to first explore which form suits you, you can use the Selection guide for private and group sessions, where you immediately see which supervisors, locations, and options match your preferences.
Individual psychedelic sessions
Full attention and alignment with your process
One of the most chosen forms is a Individual psychedelic session with personal guidance. Here, you work one-on-one with a supervisor, allowing maximum space for your process.
This shape is especially suitable if you:
want more depth without the distraction of others
specifically want to work on personal themes
need rest, safety, and full attention
During the preparation phase, we look together at factors such as mindset, lifestyle, nutrition, and intention. Based on this, we determine the best approach. During the session itself, we guide you where necessary but also leave space for your own inner process. Afterwards, we focus on integration so that insights truly gain meaning.
Location: at home or at one of our places
You can choose a session at your home or at one of our locations. Frequently used places are the Psychedelic Loft in Schiedam, The Bedding in Den Bosch and Sancta Psychedelica in Noordwijk.
Sessions at our locations include an overnight stay with food and drinks, which is especially convenient if you are coming from further away or want to be completely unburdened.
Duo sessions: experiencing together, each with their own process
A middle ground between individual and group
For those who wish to participate together, there is the possibility of a duo session for couples, friends or family members. This is a nice middle ground between an individual session and a group ceremony.
You share the experience with someone you trust, but there remains room for everyone's own process. That makes this format both connecting and deepening.
Duo sessions are often chosen by:
couples who want to deepen their relationship
friends who want to share a meaningful experience together
family members who want to grow closer
Relationship-oriented duo sessions
With couples, we often work with a two-phase structure. First, the emphasis is on the relationship with yourself, and then on the relationship with the other person. This ensures that personal insights sink in before being applied to the mutual dynamic.
This approach makes duo sessions particularly suitable for people who not only want to experience something together, but also want to consciously invest in their relationship.
Practical implementation
In most cases, one support worker is sufficient for two people. When there is a need for more individual attention or a more intensive program, two support workers can be chosen. This is a customized approach that we discuss in advance.
As with individual sessions, preparation, guidance, and integration are included. Here too, we can extend programs to multiple sessions or a multi-day format.
Group sessions: ceremonies and retreats
The power of the group
In addition to private sessions, we also offer group sessions, truffle ceremonies and multi-day retreats on. In this setting, you work with others on personal growth.
What many participants experience is that the group provides an extra sense of safety and connection. You are not alone in your process, which can make it easier to let go and go deeper.
Truffle ceremony or retreat
Within the group sessions, you can choose between:
a two-day truffle ceremony
a multi-day retreat with extra integration days
Retreats offer more room for deepening, preparation, and integration. This makes them suitable for people who want to work more intensively with their process.
What is included
For group sessions, everything is fully taken care of. Think of:
preparation based on intake
Guidance by two experienced guides
music, breathing and other deepening techniques
overnight stay and meals
integration interview afterwards
This allows you to focus fully on the experience itself.
Our team of supervisors
Experience and diversity in background
Our team consists of counselors with diverse backgrounds, including psychology, coaching, and psychosocial counseling. This allows us to determine the best style for each individual.

The team includes, among others:
Marcel van der Putten, founder and highly experienced facilitator
Ronald Hochstenbach, psychosocial therapist
Sascha de Waal and Reineke Brandt, both psychologists
Gijs Tecklenburg, with a background in mental healthcare
Janneke van de Geijn, confidential counselor and supervisor
What connects them is not only knowledge, but above all the ability to create a safe and attuned setting.
Participant experiences
The experiences of participants often provide the best picture of what a session can mean.
A participant wrote after a group session:
“With this ceremony, I not only saved my future, but also healed my past.”
Another indicated:
“They managed to create an atmosphere in which I felt 100% safe.”
And about a private session it was said:
“I felt supported without pressure, which allowed me to go deeper into my own process.”
You can read more experiences via the reviews of psychedelic sessions on the Tripforum.
Which shape suits you?
The choice between individual, duo, or group depends on what you are looking for:
If you want maximum depth and personal attention, an individual session is often the best fit.
If you want to share an experience with someone, a duo session is a logical choice.
If you want to experience the power of a group, a ceremony or retreat might be suitable.
If you are still unsure, the aforementioned decision aid will help you gain insight into the possibilities.
Finally
Psychedelic sessions can be a powerful way to turn inward, break patterns, and gain new insights. The form in which you do this makes a big difference.
At Triptherapie, we therefore always look beyond just the session. We guide the entire process, ensuring that the experience does not stand alone, but becomes part of a larger process of personal development.

Why choose Triptherapie?
At Triptherapie, you don't buy a 'trip', but invest in yourself. We view a psychedelic session not as a standalone event, but as the linchpin of a transformative journey. Since our founding, we have developed a unique method that combines science, psychology, and a deeply human approach.
What distinguishes us as the most trusted provider in the Netherlands rests on the following pillars:
1. Pioneers with unparalleled experience
We have been since 2018 active as a provider of psychedelic sessions. This was long before the current 'psychedelic hype' began. Our heart lies with the profession, even in times when there was little public interest in it. By now, we have more than 3,500 clients (and according to recent data, even approaching 3,700) have had the privilege of guiding, primarily in therapeutic processes. This vast amount of practical experience with diverse requests for help and psychological processes is unique in the Netherlands; we know what we are doing, even when a journey becomes intense.
2. A team of trained professionals
Our team consists of therapists with diverse backgrounds in healthcare and psychology. We do not believe in fleeting commercial tripsitter courses; our staff is Internally trained and intensively onboarded to ensure our quality standard.
-
Broad expertise: Thanks to our various fields of expertise, we can offer diverse supportive therapies alongside the psychedelic session.
-
Additional training: Various therapists have received additional training via RINO (therapeutic work with psychedelics).
-
Safety first: All our supervisors are trained in FIRST AID and EBDD (First Aid for Alcohol and Drugs). With us, you are literally and figuratively in safe hands.
3. The TRIP method: Scientific substantiation
We look beyond the psychological aspect. A healthy mind needs a healthy body. That is why we offer:
-
Neurotransmitter advice: Based on your intake, we look at your neurochemistry. We advise on nutrition and supplements to balance your neurotransmitters (such as serotonin and dopamine) before the session begins.
-
Customization: No two sessions are the same. We work with legal substances (truffles, psiloflora, or LSD analogues) and carefully adjust the dosage to your needs and experience. We often use a stepwise dosing during the session, so that you can calmly settle into the experience. Thanks to our experience, we also dare to safely guide higher dosages, where appropriate.
4. Privacy and Small Scale
Whether you choose an individual path or a group ceremony, privacy and personal attention are guaranteed.
-
Small groups: Our ceremonies consist of maximum 6 people, which ensures sufficient space for your own process and personal therapeutic attention.
-
Location selection: We have beautiful locations of our own (such as the Psychedelic Loft), but also offer the possibility for home visits or sessions in a nature cabin. Furthermore, for many of our ceremonies, there is the option to stay overnight at no extra cost, allowing you to integrate in peace.
5. Holistic Care and Integration
The process does not stop when the effects wear off. The real change takes place during the integration.
-
Personal contact: We remain available. From the initial registration until well after the session, we offer aftercare and coaching to help you translate your insights into your daily life.
-
Additional floor: During the sessions, we use supporting tools such as aromatherapy, color therapy, and carefully curated music to enhance the depth of the journey.
-
Loving presence: As our clients often attest: we are not 'airy-fairy hippies'. We are down-to-earth, honest, and sincere professionals who are lovingly present at the moments you need us.
Are you ready to take the next step in your personal development? Our approach is honest, ethical, and always focused on your growth.
