About me
Chemistry and biochemistry. That is my field of study. However, after completing my education, I went on to do something completely different: retail and providing service in the gaming console world. Alongside managing various webshops and tinkering with game consoles, I always maintained my scientific interest in (bio)chemistry in combination with sports, nutrition, and the overall well-being of people. Driven by 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 began applying this knowledge to help people holistically. After gaining more and more knowledge and experience with psychedelics (magic truffles) myself, 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 total approach became even more holistic. The demand for these types of programs was high, and so the education as a foundation, the enduring interest in biochemistry, the power of psychedelics, and my own drive for health fused into trip therapy.

Specialism
In recent years, I have specialized most in depression and negative self-image, and how these operate at the cellular level. Depression can have various causes, including diet, medication, illness, and emotional setbacks. The mind, or in other words your mindset, can make your body unhealthy and thereby trigger depression through inflammation. It also works the other way around: depression or inflammation in the body leads to negative thought patterns. You can utilize my knowledge and services to escape the negative spiral of depression. Currently, I am attending lectures on the combination of behavior, biology, and evolution. These reveal that much of our behavior extends beyond just our own lives. I apply this new knowledge to new sessions.
My approach
The aapak plan is based on the (medical) information you provide to me during the digital intake. I use the results of the intake and your data to determine if you are deficient in certain substances, and if necessary, you will receive advice regarding nutrition, supplements, herbs, exercise, and/or lifestyle. I aim to address the whole picture, which encompasses the entire body (and mind). During a trip session, the beginning will resemble talk therapy. After the ingestion, we will communicate less and less, eventually leaving words aside; after all, it is 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 position myself as a calm and safe energy that supports you and gently guides you where needed. As you sober up, we will cautiously resume conversation and explore together what your psychedelic experience can mean for you.
My own experiences with psychedelics
To be able to do this work driven by my own interest, I have taken about 140 trips. Most were not very high-dosed but were intended to learn more about the psychedelic state and the services associated with psychedelic therapy. A number of higher-dosed trips have certainly helped me gain insights. Here is a brief overview of myself and how psychedelics have helped me.
I had a beautiful childhood. Perhaps my parents were sometimes a little too strict and I occasionally received a hefty corrective slap. In my opinion, I never really suffered from trauma or anything of that nature. Nevertheless, everyone's behavior changes, and mine included, based on past circumstances. During several psychedelic trips, I relived these circumstances, but never as something very painful. I value myself today, and that means I must also value everything I have been through; after all, it has made me the person I am. So I have accepted the past, because there are only two options:
1: You will have to change the things you cannot accept.
2: You will have to accept the things you cannot change.
Now, the above is just a single insight I have gained due to psychedelics, among other things. But there are many more insights that have made my life pleasant.
I was able to process the loss of two loved ones during a trip. The ceremony I witnessed with my eyes closed was an indescribably beautiful farewell. From grief to happiness. From repressed memories to honoring cherished beautiful moments.
Another beautiful insight is that I used to believe that wealth and finances are the most important things. I worked myself to death to accumulate money. It is something our society encourages: individual achievement and self-enrichment. That came easily to me, but it gave me no satisfaction. Psilocybin truffles have made me realize that it is actually about connection, not isolation. Loneliness actually leads to unpleasant symptoms and addictions. Psychedelics are about connection!

Experience with psychedelic sessions
I am the founder of triptherapie.nl, and as such, I have already been working at this relatively young company for 4 years. Before starting triptherapie, I personally gained 7 years of experience with psychedelics and guidance. Altogether, I have guided nearly 1,500 people over the years so far, and I have been working (more than) full time since the company's inception.
I would also like to share some insights I gained during my work as a trip guide:
- Our reality is what you think it is. The world is heaven and hell at the same time. If you focus on the heavenly aspects, the chances increase that you will experience heavenly things and be able to recognize them in this world. That is how the βlaw of attractionβ works. We therefore co-create reality.
- Everyone has a different trip and believes in different things. It is an interpretation of information. Precisely that interpretation is merely 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 shaped by the circumstances that were and are present. For instance, depression and burnout are a perfect message from the body that something needs to change. In that case, psychedelics are not the solution, but the key to the solution in the subconscious mind.
- Let us not think in terms of broken things or things we lack. Let us, however, think about the things we do have. Everything is a gift, and life itself is too.
- The purpose of life? That is life itself. There is ample room to give it your own purpose. That can be a burden or a tremendous freedom! Some people receive an insight in this regard, and it feels like a given.
- Life, just like a psychedelic trip, is a journey. It is not about the destination.
- Good and evil is all in the beholders eye!
