David Berceli, the creator of Tension & Trauma Releasing Exercises (TRE), is actively engaged with the FDNY (New York City Fire Department) to help firefighters manage trauma and stress. TRE is a technique that utilizes the body’s natural tremor mechanism to release tension and trauma.
Firefighters are teaching other firefighters TRE, suggesting a widespread adoption of the method within the department.
