Core Transformation Licensed Trainers

All trainers listed on this page are Licensed to use the Core Transformation Trainer Materials Packet (CTTMP). All have access to these detailed and extensive Trainer Materials. These materials are an essential background to offering you a high-quality training. These trainers have not gone through a specific mentorship and review process to become an endorsed Trainer. (Some live on other continents, making this impractical). However, many (if not most) are highly experienced and capable Trainers, having developed their Trainer skills through a variety of routes. We encourage you to read their biographies below to learn more about each trainer. Whenever possible, we suggest getting a direct experience of the Trainer you are interested in. Many offer free public presentations.
