The Costello Method™: Built in Motion, Then Measured.

The Families Who Find Me Have Usually Tried Everything Else

Many of the people I work with have already tried therapy, medication, and behavioral strategies. They have worked hard. Their systems are doing everything they can. And true access still feels out of reach. That is where my work begins.

What I developed over 25 years is now known as The Costello Method™. It starts with the nervous system at the level of input, so behavior, strategy, and everything else has something steady to build on.

People come my way with or without a formal diagnosis. Some can name exactly what they are facing. Others just know something is not working. Beneath all the labels is a nervous system that has not yet been calibrated and is struggling to keep up with daily demand.

Before this method had a name, I spent years working with the body-brain connection and kept meeting the same thing. People who looked well organized on the outside and still felt off inside. That sent me toward what standard care tends to skip, the role of movement and early neuromotor development in how a nervous system learns to receive, process, and respond.

Pre and post movement assessments. Not surveys. Not parent reports. Measured outcomes.

Every number above comes from the Costello Neuromotor Baseline™ (CNMB), our own movement-based assessment, given before and after the program. It measures how the body organizes and responds through movement. It does not measure diagnoses or symptoms.
