To teach TRE to others, you must be certified. The complete certification requirements can be found on traumaprevention.com:
One of the requirements are two 3-day workshops (module 1 & 2), which are available around the US and globally. Check here for complete listing.
There are currently no TRE trainers in Oregon. However, Susan Shifman (TRE trainer, Arizona) has certified several people from Oregon, and regularly holds training workshops in our state.
