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 4-day training 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.

Hans van Wechem, MD

Hans has over 30 years of experience in the psychiatric field and has been working as a psychiatrist in his own private practice since 2003.
