The Triptherapie therapists who offer a PAT/PAP-style psilocybin trajectory with preparation and integration are: Ronald Hochstenbach, Sascha de Waal, Reineke Brandt, and Gijs Tecklenburg.
In short: Ronald Hochstenbach is a psychosocial therapist active around Eindhoven and Den Bosch; Sascha is a psychologist available around Amsterdam and Bussum; Reineke is a psychologist working around Rotterdam and The Hague; Gijs is a psychiatric nurse based around Den Bosch.
These practitioners provide a structured process with intake, a preparation conversation, a guided truffle session, and an integration talk. With Sascha, Reineke, and Gijs you can request extra or longer talk-therapy sessions before and after the session.
Hope this helps.
