I will be training in TRE in May (part 1) and August (part 2) of 2020. I will be teaching a few group and private classes for my certification. If you know that you are interested in those classes, please send an email to firstname.lastname@example.org to let me know. I will be sending out a newsletter announcement about the classes when the time comes.
In the meantime, here are two videos to get you started.
