the people behind

Our team

Jeanine & Hans

After experiencing the power and potential of psychedelics themselves for a number of years Jeanine and Hans founded Experiential Training Institute in 2022, as an experiential education company dedicated to train mental health providers in psychedelic processes.

Their pilot was for graduated students of Integrative Psychiatry Institute. During this 5-day retreat program, the mental health providers experienced both the role of the facilitator and of the client and the importance of screening, preparation and integration. Soon after, ETI extended their offer by providing both individual, as well as 3-day retreat programs for small groups, without the training component, aimed at personal growth and development.

Understanding the science, history, philosophy, psychology and psychiatry as well as the sacred wisdom linked with psychedelic work, has taken years. Both Jeanine and Hans understand first-hand the non-ordinary state of consciousness and its opportunities as well as the unique challenges that come with altered states.

How they met

Jeanine and Hans met when they worked together for Field Trip Health in Amsterdam, where they teamed up as Medical Director (Hans) and Head Therapist (Jeanine). At Field Trip, hundreds of clients were safely guided during their magic truffle sessions, with a proven track record for leading safe and legal psychedelic sessions for many individuals from all over the world. Their work in the psychedelic field deepened and strengthened as they shared a collective inspiration and purposefulness of doing profound transformative work together.

This experiential training was profound in so many ways. I experienced so much growth, both personally and professionally. Jeanine and Hans were incredible, I felt safe and supported the entire time. I am leaving changed for the better. Thank you!

Erin H, - Psychologist Phd

I was deeply inspired by the depth of healing & connection cultivated in such a short time... wow. "the Journey within the Journey". Coming to the Netherlands from the US allowed me to be far enough from the various stressors of daily life to be fully present and completely immersed in the experience. It required me to step out of my comfort zone and truly commit to myself here. Powerful!

Mindy T. - Psychologist

Hans and Jeanine are such a dynamic team, with depths of knowledge and a passion for training. I learned so much about the medicine and myself. I think the way they set up the event was very thoughtful. I really appreciated the medicine followed by the breath-work. I was out of my comfort zone in so many ways, not only was trusts the process experienced in the medicine journey, it was also felt meeting the group and doing interventions in this space feeling so open and so vulnerable. Jeanine and Hans held the space for people to feel their emotions and step into embodying the essence of trust the process.
