I am Janneke van de Geijn and work as a facilitator at Triptherapie. My path to facilitating psychedelic sessions is one of transformation, deep life experience, and a strong drive to help others in their growth. I am caring by nature; caring for others is in my blood. I worked in healthcare from a young age, but due to physical circumstances, I had to leave this field behind. Nevertheless, I found a new form of service, ultimately in guiding people during psychedelic sessions.

After an intense period of personal change, including a divorce, I began to reinvent myself. That phase brought me closer to my core and led to a calling: guiding people towards more balance, self-insight, and healing. I delved into lifestyle and psychology and obtained the OERsterk lifestyle coach diploma. I am currently pursuing a Bachelor's degree in Applied Psychology, specializing in Psychology and Health.
During my own psychedelic experiences, I discovered how profound these journeys can be. I overcame my fear of losing control and found healing in layers that no other form of therapy could reach. The insights I gained there—self-love, forgiveness, direction, inner peace—have changed my life. I wish that experience for everyone.
My approach is warm, honest, and intuitive. For every session, I create a tailored lifestyle plan, including nutrition tips, hormonal and neurochemical support, and inspiration in the form of videos or podcasts. During the session, I create a safe and respectful environment where you are free to feel and discover whatever is needed at that moment. And after the session, I stand beside you to integrate together what has surfaced.
I work from Vlaardingen and offer sessions within a 45-minute drive, including in Rotterdam, The Hague, Delft, Gouda, Dordrecht, and Hoek van Holland. I work with psilocybin, MDMA analogues, and combinations such as Hippie Flip and Psiloflora, both individually and in pairs.
Clients describe me as a calming presence, maternal, intuitive, and engaged. I ensure that you feel safe and dare to let go. As one client wrote: “Janneke made me feel completely safe. She was truly there for me. I could never have done this alone.”
