Hein Pijnnaken is a Transformational Coach, NLP Master (advanced), and microdosing educator & coach. While growing up in the Netherlands—one of the most psychedelic-friendly countries in the world—he became familiar with psychedelics in his early college years and has used them as transformative tools ever since. Today, he has over 30 years of experience guiding psychedelic sessions and has immersed himself—both theoretically and practically —in the topic of microdosing since 2016. He strongly believes microdosing is an incredible tool for self-development, especially in combination with effective coaching.



Jakobien van der Weijden is a Certified Holistic Coach, psychedelic guide, and microdosing educator & coach. She has been in service of the psychedelic renaissance since 2003; thoroughly studying entheogenic plants, promoting psychedelic research, and studying the many modalities that support safe and effective psychedelic therapy. She has been attending plant medicine ceremonies from different traditions since 2008 and continues to deepen her understanding of psychedelics and the human psyche ever since. 

In previous roles at organizations such as OPEN Foundation, Psychedelic Society of the Netherlands, Synthesis Institute, and now at the International Microdosing Association, she developed close relations with scientists, therapists, and knowledgeable facilitators across the planet.
