Clinical practice shaping the method
Dr. Jim CostelloCreator of The Costello Method™
For 25 years, Jim Costello worked in clinical practice in sports medicine, pediatric care, and addiction recovery. He kept running into the same problem: patients with ADHD, anxiety, kids who couldn't regulate, adults who couldn't calm down no matter what they tried. The clinical tools of the time had no answer for what he was watching.
The answer came from an unlikely place. Working with horses, 1,500-pound animals that take direction entirely from the state of your body and not your words or intentions, he saw the nervous system in its clearest form. A dysregulated rider produces a dysregulated horse. No amount of effort or intention changes it. The body leads. It always has.
He spent years reverse engineering that. What specific inputs move a system out of protection? What does the body need, in what sequence, to give the brain something it can actually use? That work ran through addiction recovery, through pediatric ADHD and ASD, through executives and athletes and parents who had no language for what was happening inside them. The methodology held in every room.
That's what became The Costello Method™. That's what STILL is built on.
"The insight that changed everything didn't come from a clinic. It came from a 1,500-pound horse."
"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."

As Featured In
Your brain doesn't lead your nervous system. It follows it.
You've read the books, tried the therapy, and built the routines. You've taken the medication and done the breathing exercises at 2am when your mind just wouldn't stop.
Some of it might have helped for a while, but the relief always wore off.
Here is what nobody told you: every one of those approaches started from your head, trying to think their way into your body.
Meanwhile, your nervous system wasn't waiting for your brain to catch up. It has been quietly and constantly stuck in a state of protection underneath it all.
- You've tried everything and it helped a little but never fully.
- You are struggling with ADHD, ASD, or sensory challenges.
- Your body changed in your late 30s or 40s and nothing has worked the same.
- You function and manage, but you haven't felt like yourself in a long time.
You aren't broken, and it isn't a lack of willpower. It's simply what your nervous system has access to right now.
Why Everything Else Failed
Most approaches are "top-down." They ask your brain to convince your body that it is safe. But when your nervous system is stuck in protection mode, it does not listen to logic. It only listens to physical inputs.
The Costello Method™ is a "bottom-up" approach. We use precise neuromotor movements to bypass the mind and speak directly to the nervous system in its own language. When you change the physical inputs, your body finally gets the signal to stand down, and the brain naturally follows.

Discover your Nervous System Archetype
Your body responds to stress in one of three ways. You cannot shift a state you have not named. Click an archetype below to see if it resonates.
Running in constant overdrive. You can't fully relax even when nothing is wrong. Your body has forgotten how.
Running on fumes. You're keeping it together, but one small thing away from breaking.
Shut down. Your system went numb to protect you. And now you can't feel the things you want to feel either.
Your body has been sending signals for a long time. STILL is how you finally answer them.
Most members report feeling a measurable shift within their first week. You do not have to stay stuck in survival mode.
