What participants say

Feedback from therapists who attended these trainings.

Just like the last time, this two day training was filled with the passion of Suzy and Ad. I was able to gain a lot of new knowledge and vitality from both of them. As I learn EMDR 2.0, my EMDR therapy is becoming more efficient and powerful.

Seoul, Korea · 2026

This was one of the best trainings I’ve attended over the last 10 yrs. Having looked at their papers and evidence for the results it is clear that WM theory and EMDR 2.0 are major advances that are opening new possibilities for clients to achieve a full recovery from trauma. Amazing stuff!

London, United Kingdom · 2026

This training has been the most revolutionary in my practice after years of working as a therapist. I know there’s not a “magic wand” but this is as close as it gets!!!
