Mental health begins with the body.
Dr. Jim Costello has spent more than 25 years working directly with thousands of children and adults. The Costello Method is what came out of it: a foundational model of how your nervous system receives, processes and responds.
"The Costello Method helped me reconnect with myself in a way nothing else had. If you're feeling disconnected or stuck, it's something I truly recommend."
Chris Martin, Musician, Coldplay
As Featured In
Receive. Process. Respond.
Every moment, your nervous system receives signals from the world around you, processes them and responds. When that sequence is organized, you have Access. When it is overloaded, you feel it as overwhelm, focus that won't hold and sleep that doesn't restore.
The Costello Method™
Defines the model: how your nervous system receives, processes and responds.
Neuromotor Calibration™
Puts the model into practice through simple, guided movement.
Costello Neuromotor Baseline™
Measures it: a structured baseline of how your system is working.
Not a fitness program, physical therapy, psychotherapy or a diagnostic system. A body-first model of foundational neurological function.
Overwhelm has an architecture.
When daily demands outpace your ability to receive, process and respond, day in and day out, you feel the gap as overwhelm.
