Rachel Harrington, COTA/L, CPRCS, is a pediatric occupational therapy assistant, certified primitive reflex clinical specialist, educator, entrepreneur, speaker, and mom of two who is passionate about helping families understand the connection between the nervous system, sensory processing, primitive reflexes, movement, and healthy living. Through her years of working with children and parents, Rachel has seen firsthand how overwhelming modern life can feel, not only for children but for the adults raising them.

Rachel is the founder of The Sensory Project and the owner of Sensational Brain, where she provides continuing education, sensory and primitive reflex resources, as well as practical tools for parents, therapists, and educators around the world.

Known for translating complex neuroscience into simple, practical strategies, Rachel specializes in sensory processing, primitive reflex integration, self-regulation, childhood development, and movement-based interventions. She is the author of the Crawling for Brain Development curriculum and has written several children’s books, including The Jungle Crawl, The Dino Crawl, and The Unicorn Crawl, which focus on sensory and primitive reflex integration through interactive story time.

In her latest book, Grounded: A Nervous System Regulation Guide for Overstimulated Parents, Rachel combines her professional expertise with her own personal experience to help parents better understand themselves, support their children, and create calm in the chaos of modern parenting.

But beyond the credentials, courses, and businesses, Rachel is a mother navigating the same mental load, sensory overload, exhaustion, and emotional demands that so many parents silently carry. Her work is deeply rooted in the beliefs that parents deserve support too and that understanding our nervous systems can help us move from surviving to feeling more grounded, connected, and regulated in everyday life.
