Core Transformation was created by Connirae Andreas. Clients may appreciate knowing about these other resources for learning Core Transformation from Connirae and her sister Tamara, as well as other trainers around the world:

Core Transformation: Reaching the Wellspring Within by Connirae and Tamara Andreas.
The original and still definitive manual on learning to do Core Transformation with yourself or even with clients if you are a coach or therapist. If you are strongly motivated, this may be all that you need. Highly recommended.

Core Transformation: The Full 3-Day Workshop on DVD with Tamara Andreas.
A recorded workshop lead by Tamara Andreas, the world’s foremost Core Transformation trainer. Not quite as engaging as being there live, but quite a bit cheaper and still very good. Includes the best available recorded training on an additional process called Aligning Perceptual Positions, also created by Connirae Andreas.

The Core Transformation official website.
Includes listings of all licensed and endorsed Core Transformation trainers worldwide, a few articles, and other resource materials.
