Susan Koen, Ph.D., is a psychologist, author, and speaker whose work explores the profound terrains of love, death, courage, and human connection. For decades, she served as a researcher and management consultant, helping individuals and organizations understand circadian rhythms and the neuroscience behind human errors and safety lapses at work.

Her life and career took a transformative turn when her beloved partner of forty years was diagnosed with a genetic brain disorder, the GRN version of Frontotemporal Dementia (FTD) known clinically as bvFTD. As Susan became her primary caregiver, she entered a chapter marked by advocacy, tenderness, humor, and the emotional complexity of witnessing someone you love slowly disappear.
