Susanne Cook-Greuter

Susanne Cook-Greuter is a Harvard developmental psychologist whose pioneering research expanded Jane Loevinger’s stages of ego development, identifying two additional advanced stages. She has a nuanced understanding of higher development, a rigorous approach to the science behind it, and a delightfully authentic and playful spirit. All three have inspired, instructed, and influenced me and many other serious students and teachers of Integral theory.
