Richard and Niall discussed Niall's book on experiential therapy for treating trauma, which outlines 15 different therapeutic approaches and their applications. They explored the value and criteria of experiential therapies, emphasizing the importance of engaging the emotional brain through various prompts and techniques. The conversation concluded with plans for a webinar series based on the book, covering different therapeutic approaches over 15 months, along with promotional offers and continuing education opportunities for practitioners. Niall also offers a 15% discount on the webinar series using the code "SOP15" and a 30% discount on the book through Routledge Press, available on the website experiential-psychotherapies.com.
