I've heard about it. Read about it. Attended conferences that had presentations about it. I've heard Jeffery Young speak about it but unfortunately, not in person.
I really like the techniques and philosophy behind this style of therapy. Sadly, not many therapists are trained in the technique across the U.S. Seems to be small pockets of therapists who have been trained but it isn't as widespread as DBT. As already mentioned, DBT teaches the skills needed for self-regulation and social skills and Schema Therapy goes deeper and allows people to make important changes in how they think, act and understand themselves. You're very lucky to have found someone trained in the techniques!
