Russ Hudson has established himself over the past three decades as one of the top teachers and developers of the Enneagram personality typology in the world today. Actively involved in the Enneagram community, Russ is co-founder and president emeritus of The Enneagram Institute, as well as a founding director and former vice president of the International Enneagram Association. He's been writing and teaching full time with The Enneagram Institute since 1991.

Russ has co-authored five bestselling books with Don Richard Riso, including The Wisdom of the Enneagram and Personality Types. These books are widely considered to be not only groundbreaking contributions in the field of Enneagram studies, but also important contributions to the literature of psychological types. The pair developed a scientifically validated test instrument, the Riso-Hudson Type Indicator (RHETI), now considered a standard test in the Enneagram field. The RHETI has been used by numerous Fortune 500 companies.

Russ has a solid background in science, as well as in studies of philosophy and religion. He approaches his work with the Enneagram holding both perspectives. He originally encountered the Enneagram through The Gurdjieff Work, and sees it as a map for personal development and awareness rather than merely a system for categorizing people. He has emphasized the importance of cultivating presence and mindfulness as a foundation for authentic work with the Enneagram, and has worked diligently to align the study of the Enneagram to spiritual practice — and to bring the benefits of this synthesis into greater public awareness.

Russ has been interviewed as an expert on personality types on several dozen radio and television shows, including Good Morning America and The CBS Morning Show. He has become a popular speaker at conferences and retreat centers around the world, including the Esalen Institute, the Wisdom 2.0 Conference, and the Science and Nonduality Conference (SAND).
