ACT:Root to Fruit
Marcel Tassara, PhD
Frequency: 1 episode/28d. Total Eps: 37

Do you like Acceptance and Commitment Therapy and feel like your keep missing the nail?
Want to:
- Get grounded in the foundation stones?
- See contingencies?
- Add context?
- Be a functional contextualist? (and know what that means)
This is a new podcast that seeks to excavate the roots of the contextual behavioral sciences, so that the fruit that us clinician deliver is as pristine as possible. It's a sequential experience that takes non-congenital behaviorists beyond the 6 core processes, and just saying "milk, milk, milk". Many of us that come to ACT/CBS don’t get past the razzle and dazzle...Well, walk with me on this quest and lets play with the boring that the razzle dazzle is built on.
- New episodes published weekly starting 7/20/2020
- Experiential work in (just about) every episode
