About me

Chemistry and biochemistry. That is my field of study regarding schooling. After finishing my education, however, I started doing something completely different, namely retail and service in the game computer world. Besides managing several web shops and tinkering with game computers, I always kept my scientific interest in (bio)chemistry in combination with sports, nutrition and the general well-being of man. From this interest I have been reading and studying scientific research on diseases, nutrition, sports, herbal medicine, phytotherapy, psychology and general well-being for over 10 years. I started using this knowledge in order to help people holistically. After I myself gained more and more knowledge and experience with psychedelics (magic truffles) everything fell into place. Psychedelics fit perfectly into a healthy lifestyle and deserved a place in coaching for both physical and mental health. The idea behind trip therapy was born and the overall approach became even more holistic. Demand was high for this type of pathway and so the education as a foundation, the continued interest in biochemistry, the power of psychedelics and my own drive for health merged into trip therapy.

In recent years, I have most specialized in depression and negative self-images and how they work at the cellular level. Depression can have several causes, including diet, medication, illness and emotional setbacks. The mind, or in other words your way of thinking, can make your body unhealthy and therefore trigger depression through inflammation. It also works the other way around, depression or inflammation in the body in turn triggers negative mindsets. You can use my knowledge and services to escape from the negative spiral of depression. I am currently attending lectures on the combination of behavior, biology and evolution. From these, it appears that a lot of our behavior goes beyond just our own lives. I am applying this new knowledge to new sessions.

My approach

The plan of action is based on the (medical) data you give me during the digital intake. I use the results of the intake and your data to see if you are missing certain substances and if necessary you will get advice from that regarding nutrition, supplements, herbs, exercise and or lifestyle. I try to address the whole picture, which is the whole body (and mind). During a trip session, the beginning will be similar to talk therapy. After the intake, we will start to communicate less and less and eventually we will leave the words for what it is, after all, it is all about the experience. During a trip session I may use music, light, herbs and/or aromatherapy to achieve our pre-agreed goal. My presence will be subtle and I set myself up as a calm and safe energy that assists you and lightly adjusts you where needed. While sobering up, we will re-enter into gentle conversation and explore together what your psychedelic experience can do for you.

My own experiences with psychedelics

To do this work because of my own interest, I did about 140 to 150 trips. Most of them were not very strongly dosed but were intended to learn more about the psychedelic state and the services associated with psychedelic therapy. Some higher dosed trips did help me gain insights. Herewith in brief a little about myself and how some psychedelics have helped me.

I had a beautiful childhood. Maybe sometimes my parents were a little too strict and I do get a hefty corrective slap sometimes. In my opinion, I never really suffered from trauma or anything like that. Still, everyone's behavior, and so did mine, changes based on previous circumstances. During several psychedelic trips I have re-experienced these circumstances, but never as something very painful. I appreciate myself today and that means that everything I have experienced should also be appreciated, after all it has made me the person I am. So I have accepted the past because you there are only two options:

1: The things you cannot accept you will have to change
2: The things you cannot change you will have to accept

Well the above is just a single insight I have gained because of psychedelics, among other things. But there are many more insights that have made my life pleasant.

I was able to cope with the loss of two loved ones during a trip. The ceremony I watched with my eyes closed was a beautiful farewell that cannot be described. From grief to happiness. From memories pushed away to honoring remembered beautiful moments.

Another great insight is that I used to believe that wealth and finances were the most important thing. I worked myself to death to accumulate money. It is something our society encourages. Namely individual achievement and self-enrichment. That came easily to me, but it was not satisfying. Psilocybin truffles made me realize that it is all about the connection and not the loneliness. Loneliness actually leads to unpleasant symptoms and addictions. Psychedelics are about connection!

Experience with psychedelic sessions

I am the founder of triptherapie.nl and I have therefore been with this relatively young company for 5 years. Before starting trip therapy, I have already had 7 years of experience with psychedelics and counseling myself. Altogether, I have counseled over 1600 people in all those years so far and have been working (more than) full time since its inception.

I want to further provide some insights I have gained while working as a trip counselor:

  • Our reality is what you think it is. The world is heaven and hell at the same time. Focus on the heavenly sides then the chances grow then you experience and know how to recognize heavenly things in this world. In that way the "law of attraction" works. So we co-create reality.
  • Everyone has a different trip and believes in different things. It is an interpretation of information. Just that interpretation is only human and also a little different for everyone.
  • Some think that psychedelics heal people but what we often forget is that everyone is whole. Psychedelics show you that you are perfectly formed according to the circumstances that were and are there. For example, depression and burnout is a perfect message from the body that something else needs to happen. Psychedelics then are not the solution but the key to the solution in the subconscious brain.
  • Let's not think in terms of piece or things we lack. Let's think about the things the do have. Everything is a gift and so is life itself.
  • The purpose of life? That is life in itself. There is plenty of room to give purpose to it yourself. That can be a burden or an amazing freedom! Some people get an inspiration in that and it feels like a given.
  • Life, like a psychedelic trip, is a journey. It is not about the destination.
  • Good and evil is all in the beholders eye!

Booking a session with Marcel at the client's location

I work all over the Netherlands. So I can be booked for sessions at your home, in an Airbnb, vacation home or a hotel of your choice. For the sessions at home I come from my current residence Noordwijkerhout and the travel expenses of 50 cents per kilometer are calculated from postal code 2211BM. Do you live far away or are you coming from abroad? In that case, you can also choose to rent a cottage/hotel/Airbnb closer to beautiful Noordwijkerhout itself. Finally, you can of course also use our location in Schiedam. Bookings at the Schiedam location include accommodation and food/drinks.
