Overview
The Enneagram Institute, founded by Don Richard Riso and Russ Hudson, is responsible for much of the modern Enneagram's theoretical framework. Their Levels of Development model and RHETI assessment are used worldwide. However, it's important to note that the Enneagram Institute does not offer a certification or professional training program — they offer workshops and intensives for personal and professional development.
