About Dr. Jim Costello

Founder of Neuro-Fit Systems, Inc. | Creator of The Costello Reset™ | Author: The Brain Follows

Many of the people I work with have tried therapy, medication, or mindset work or attempted to build new skills on top of a nervous system stuck in reactivity. Their systems are doing everything they can to cope, but true regulation still feels out of reach. That’s where my work begins

I specialize in nervous system regulation through movement. The method I developed, now known as The Costello Method, blends exercise physiology with neurodevelopmental science to create targeted protocols that help the brain and body reconnect. This approach improves focus, emotional regulation, processing speed, and resilience especially for those navigating ADHD, autism, anxiety, and chronic stress

People come my way with or without a formal diagnosis. Some can name exactly what they’re facing. Others just know something isn’t working. The bottom line is this: beneath all the labels is a nervous system that is dysregulated, overworked, and struggling to keep up with daily life. And the signs are clear

Before developing this method, I spent years in private practice as a chiropractor. I kept seeing the same thing people who looked aligned on the outside but still felt off inside. That led me to study what traditional care often misses: the role of movement and early development in nervous system regulation.
