I cannot verify a single top choice for the whole Netherlands. It depends on whether you prioritize in-session guidance or therapeutic integration afterward.
For session facilitation at Triptherapie, the most experienced guide is Marcel van der Putten with 2,400+ sessions and a focus on preparation, guidance, lifestyle optimization, and integration. You can read more about Marcel on his staff profile: Marcel van der Putten.
For integration and psychosocial support, Ronald Hochstenbach is the leading option at Triptherapie. He has RBCZ registration and training in Jungian therapy, Psychodrama, Voice Dialogue, IFS, mindfulness, and compassion-based approaches, making him well suited for structured integration and deeper therapeutic follow-up.
In short: choose Marcel for maximum in-session experience, or Ronald for integration-focused therapy. Hope this helps.
