Experienced guidance during psychedelic sessions
At Triptherapie we work with a dedicated team of experienced facilitators, supplemented by subject-matter advisors from mental health care. Together, we ensure safe, careful, and well-prepared psychedelic sessions, with attention given to both the experience and the subsequent integration.
Our guides have diverse backgrounds in psychology, coaching, therapy and body-oriented work. What unites them is extensive practical experience with psychedelic sessions, a professional attitude and a clear focus on safety, ethics and personal harmonisation.
Clear roles and responsibilities
Within Triptherapie, we make a conscious distinction between different roles:
Guides / facilitators / Tripsitters:
They guide the psychedelic sessions themselves. These are experienced professionals with hundreds to thousands of guided sessions under their belt, who work according to established protocols for preparation, setting, guidance and integration.
Therapists and coaches
In addition, some facilitators have a therapeutic or coaching background, such as psychology, psychosocial therapy, bodywork or trauma-informed methods. This expertise is utilised particularly during intake, integration and supplementary guidance. You can also have these therapists guide your psychedelic journey.
External consultants (Mental Health & clinical care)
Triptherapie works in partnership with advisers from the mainstream mental health sector. They are not involved in delivering the sessions, but provide support on substantive matters relating to safety, due care, ethics and integration with mainstream care.
Experience and expertise
Together, the team of Triptherapie over 3400 guided sessions carried out. Each supervisor works within a clear operational area and applies the same core principles:
careful intake and preparation
clear agreements on intention and setting
continuous presence and supervision during the session
focus on integration into daily life
This approach allows us to offer tailored support, whether it is for personal growth, emotional processing or deepening insight.
