ABOUT THIS EPISODE
Can Flash technique fully and permanently resolve a trauma memory in a single session, with almost no distress, even in clients with complex PTSD? Thomas Zimmerman has been answering that question for four and a half years, and his answer is yes. In this episode, he walks through the science, the structure, and the live protocol of the Predictive Processing Flash technique (formerly Four Blinks Version of Flash), with me as the client.
Thomas is a mental health therapist, EMDR consultant, author, podcaster, and trainer based in Cleveland, Ohio. He developed his version of the Flash technique, originally called Four Blinks, around a predictive mind model of the brain. He explains why that model changes how we understand trauma, memory, and healing, and why it means every client is capable of change.
We cover the four resourcing tools that make this approach safe for complex presentations, how Flash differs from EMDR in every structural and theoretical way, and what is actually happening in the nervous system during a session. Then we do a live demo. I work through a real memory in real time.
Thomas also offers free Flash trainings every two weeks, free bi-monthly consultation, and a free weekly self-care Flash group for trained clinicians. This is a conversation worth sharing with every trauma-focused colleague in your network.
