Clinician and client reference in Somatic Therapy
Format: Paperback
This book is written as an office reference. Part of this book is dedicated at the clinical level towards the professional. The book has somatic techniques for the professional with explanations. It helps the professional understand the work and identify things while working with the client. Then part of this book is written with patient hand out materials and exercises. Those sections are similar to what one would see for a client workbook.

Looks like it will be helpful
Format: Audiobook
I'm not very far into this one yet, but so far, I love it. I bought the kindle and audible versions. It is nice to be able to listen to the exercises to go through them, and to be able to look up the specifics of any exercise. With whisper sync, I can point to an exercise in the kindle, and have audible read it to me. Great. the exercises I have tried so far seem like they are going to be helpful.
