Enneagram knowledge and wisdom is in the public domain. No one owns it. Anyone can study it and teach it. There are many schools and authors of Enneagram wisdom. One can learn from any or many of these schools or authors.
The International Enneagram Association (IEA) is an organization that seeks to be an umbrella for all the Enneagram schools and authors. The mission of the IEA is to create an international community of the Enneagram, and is invested in Enneagram education for the world.
The Colorado Chapter of the IEA is the local chapter that regularly hosts events and meetup groups.
Paul Paiva has served four years on the board of directors of the Colorado Chapter of the International Enneagram Association (IEA) and is currently an associate board member since 2016
