She is the Founder of the Inner Mammal Institute and Professor Emerita of Management at California State University, East Bay. As a teacher and mom, she was not convinced by prevailing theories of human motivation. Then she learned about the brain chemistry we share with earlier mammals, and everything made sense. She began creating resources that have helped thousands of people manage their inner mammal.
