for the meltdown you know is coming.
Your child holds it together all day at school and falls apart the moment they see you.Your child holds it together all day at school
and falls apart the moment they see you.
You have not run out of options. The help came in the wrong sequence.
The Costello Method™ prepares your child's nervous system first, through movement, so the calm and focus already in them can finally show up: at the door in the morning, at bedtime, in the moments that used to fall apart. Twelve weeks, one-to-one, in Santa Monica or online.

Where the sequence breaks
The sequence breaks when the nervous system cannot receive, process and respond to what is being asked of it.
Behavioral Coaching and Skill Building
These approaches ask your child to try harder before their nervous system is ready. When the system is not stable, more effort just makes things harder. It is not a willpower problem. It is a sequencing problem.
Therapy and Medication
These tools can help. But if the nervous system is not yet organized enough to receive and use them, the results will not stick. It is not that the tools are wrong. The system just was not ready for them yet.
The Foundation the Others Are Missing
The Costello Method™ is not a replacement for therapy or medication. It builds Access first, so everything else your child is already receiving can finally take root. This is the step that was missing.
Overwhelm has an architecture.
When daily demands outpace your child's ability to receive, process and respond, day in and day out, you see the gap as overwhelm.
Receive: Signals from the world around your child
Process: How their nervous system sorts them
Respond: Protection or Access
You are in the right place if:
Your child has an ASD, ADHD, or Anxiety diagnosis and the label gave you a name but not a way forward.
You have tried therapy, behavioral supports, and medication and something is still not landing
You noticed early signs that something was off, toe-walking, poor balance, sensory sensitivity, feeding struggles, stimming, and were told to wait and see.
You can see what your child is capable of. You just cannot reach it consistently.
"You were right to notice because those were signs of a nervous system that needs support, not more time."

How It Works
Find the signature
The 3-minute Neuro-Access Quiz™ shows your child's Neurologic Signature: Braced, At Capacity, or Fatigued.
Measure it
A movement-based assessment, the Costello Neuromotor Baseline™, shows where your child's system is starting from, so we can measure change across all twelve weeks.
Recalibrate it
One-to-one movement work in three phases, Foundation, Fortify, and Fine Tune, that helps your child's nervous system take in the world and respond to it more steadily. We call this work Neuromotor Calibration™.
The Costello Method™ Three Phases
The Costello Method rebuilds in a specific order. The body has to be ready for each step before the next one can hold.
Phase 1 - FOUNDATION
We start with the reflexes your child's body never finished integrating. These are the involuntary responses that keep a young nervous system on guard, reacting to the world as if it is a threat. As they integrate, your child's system learns it is safe. The reactivity you have been absorbing all day begins to settle. The bracing eases.
Phase 2 - FORTIFY
We build the neuromotor pathways that let your child meet stress without shutting down or coming apart. This is where endurance develops. Instead of draining under the demands of an ordinary day, the transitions, the noise, the sudden change of plan, your child's system starts to hold steady.
Phase 3 - FINE TUNE
We refine how your child's body and brain communicate, so focus, emotional flexibility, and clearer thinking become reliable instead of occasional. You will not have to coach these out of your child or force them. They show up on their own once the foundation underneath can finally hold them.
Sessions are one-to-one, in person in Santa Monica and online for families outside the area.
The Costello Method™ is not a fitness program, physical therapy, psychotherapy, medical treatment or a diagnostic system. Neuro-Fit Systems does not diagnose or treat medical conditions. We work the system beneath the label.
Most approaches work from the top down. This works from the bottom up. When the system underneath is more organized, the behavior takes care of itself. Behavior is a readout, not a character report. No forcing. No managing. No asking your child to try harder than they already are.
What Families Say After 12 Weeks
"Michael had been in therapy for three years. We saw small improvements but nothing that held. Three weeks into this program something shifted. He stopped fighting us at the door every morning. He started sleeping through the night. Our house got quieter in a way I did not know was possible."
"The improvement we have seen in Miles has been incredible. Not only can he move from one task to the next without a meltdown, we have also seen real gains in his focus and his ability to sit down and work through his homework. Something shifted at the root."
"Our daughter was timid around other children. She wanted to connect but did not quite know how to step in. Midway through the program, we watched Sienna become more confident and more physically present on her own. Then one day at the park, something shifted. She walked right up to a group of kids and jumped in. She has not stopped since."
"I had been managing anxiety my whole life. I thought that was just who I was. Eight weeks in I realized I had gone three days without that constant feeling of dread. I did not even notice it was gone until it had already left."
"We had tried everything the doctors recommended. Charts, medication adjustments, therapy twice a week. Nothing stuck. What changed here was not his behavior. It was him. He stopped fighting himself."
"I kept asking myself why I had not found this sooner. Dr. Jim's approach, specific movement for a specific purpose, was exactly what I needed. I was exhausted by medication management. His system-based approach was clear, focused, and it worked."
"I could not be happier with what this program did for me. Finding Neuro-Fit Systems was one of the best things that has happened in a long time."
Start Here. Everything Else Gets Clearer After This.
The Neuro-Access Quiz™ takes 3 minutes. It shows whether your child's nervous system is Braced, At Capacity, or Fatigued, and what that means for their behavior, focus, and ability to connect.
