My Story

I spent twenty years building networks. Then two kids taught me a different kind of wiring.

James Shinn, Certified LENS practitioner and owner of BrainWerx — James Shinn

For about two decades I was a network engineer. I traced signals, found the break in the line, and got things talking to each other again. I was good at it. I thought that was the work I'd do for the rest of my life.

Then my wife and I became foster and adoptive parents, and our twins came home. They'd been through more before kindergarten than most people go through in a lifetime. The diagnosis came back: severe Reactive Attachment Disorder and PTSD. The psychiatrists were honest with us in the hardest way possible — they used the word untreatable.

I couldn't accept that. Not for my kids. So I did what I'd always done — I went looking for the break in the line. That search led me to neurofeedback. I learned it, I ran the sessions with them myself, and I watched, week after week, as the kids the experts had given up on started to settle. Started to sleep. Started to trust.

They thrived. Six years hands-on with my own family, then friends and other families, before I ever called it a business. About a year ago, I finally hung the sign: BrainWerx. Now I sit with other families walking the same road I walked — parents who've been told there's nothing left to try.

This work found me. I didn't choose it. And now I can't imagine doing anything else.

How LENS Works

LENS Neurofeedback, in four quiet steps

LENS stands for Low Energy Neurofeedback System. The whole idea is in the name — it's low energy. It's passive. You don't have to do anything right, because there's nothing for you to do.

1
You sit down. That's it.
No games. No homework. No screen you have to react to. You get comfortable in a chair and let the session happen around you.
2
Small sensors read your brain's own signals.
A few gentle sensors listen to the electrical patterns your brain is already making. Nothing goes in. They only listen.
3
LENS mirrors those signals back — at a whisper.
The system reflects your own patterns back to you at an intensity so low you won't feel it. It's a nudge, not a push.
4
Your brain sees itself — and self-corrects.
Given a clear look at its own activity, the brain does what it's built to do: it settles the noise and finds a steadier rhythm on its own.

How LENS is different from traditional neurofeedback

Passive, not active. Traditional neurofeedback asks you to concentrate and train. LENS asks nothing of you.
Often faster. Many people notice a shift in far fewer sessions than traditional training takes.
Works even when focus is hard. If sitting still and concentrating is the exact thing you're struggling with, LENS still works. That's the point.

Head LENS & Body LENS

I offer both. Head LENS works with the brain directly. Body LENS works along the nervous system out in the body — helpful for tension, pain patterns, and the physical side of stress. We decide together what fits you.

Who It Helps

If you've been told there's nothing left to try

These are the families and folks I sit with most. If you don't see yourself on this list, reach out anyway — there's a good chance we should still talk.

Trauma & PTSD

When the nervous system stays stuck on high alert, LENS helps it find its way back down to safe.

Attachment disorders (RAD)

I've walked this road

Foster and adoptive families are welcome here. I've walked this road with my own kids — you're not walking it alone.

Autism spectrum & speech

A gentle, no-demand approach that meets kids and adults exactly where they are, at their own pace.

Traumatic Brain Injury (TBI)

For brains recovering from injury or concussion, LENS offers a quiet way to help patterns re-settle.

ADHD & focus

No concentration required to receive it — so it reaches kids and adults whose focus struggles keep them from sitting still for traditional neurofeedback.

Anxiety & emotional dysregulation

For the racing thoughts and the big feelings that arrive without warning and won't quiet down.

Sleep & brain fog

When rest won't come and the mind feels clouded, a steadier nervous system often means deeper sleep.

Depression

A drug-free path worth exploring alongside the care you already have, never in place of it.

Peak performance

Used by professional sports teams, elite athletes, and special forces to sharpen response time and recovery.

Dementia

For cognitive slowing and memory support in aging adults.

Addictions

For substance and behavioral addiction recovery support.

What to Expect

Your first visit, start to finish

If you've never done this before, here's exactly how it goes — so nothing about it feels like a surprise.

1
Arrive
You come in, get comfortable, and settle. We talk for a minute so I know how you're doing today.
2
Relax
You sit back in the chair. No screen to watch, no task to get right. Some people close their eyes.
3
Sensors placed
I place a few small sensors. They're gentle and painless — they only read what your brain is already doing.
4
Gentle feedback
The LENS signal runs at a very low intensity. Most people feel nothing at all while it works.
5
Done
Thirty to fifty minutes and you're finished. You get up and go on with your day — no downtime.

30–50

Minutes per session

Every session runs 30 to 50 minutes — long enough to do the work, short enough to fit into your day. I give you the time you actually need.

Nothing to do right

There's no effort required. You can't do a session wrong, because there's nothing you have to perform.

Safe & non-invasive

Nothing enters your body. It's a listening-and-reflecting process with no known side effects.

You set the pace

We go at the speed that feels right for you or your child. This is a calm place, not a clinic on a clock.

$125

Per session, flat

Same flat rate whether a session runs 30 minutes or 50. Book a time that works, and come as you are.

Add on: Photobiomodulation — $25

Red-light therapy during the same session. No extra appointment, no extra chair time.

In Their Words

Quiet changes, one family at a time

A family's story

“Trauma left my son unable to speak & me crippled with anxiety. A few sessions with James & my son started talking... & I went from wired to completely laid-back. This gentle work transformed both of us.”

Mother & client · Chattanooga

On feeling the difference

“On the drive back, I could actually breathe. I saw colors again.”

Nurse · Nashville

For the racing mind

“Went from Pantera to chilled-out Sade vibes after one BrainWerx session.”

Drummer · Chattanooga (California transplant)

Body LENS

“I'm a massage therapist & my shoulder pain was relentless — 9/10 by the end of the day, 6-7 clients per day. After a few BodyLENS sessions the pain doesn't climb above a 2/10 anymore. James helped my body finally let go of that pattern.”

Gauging interest

Would you rather I came to you?

I'm in Chattanooga, and nothing's signed anywhere else. I'm just seeing where the demand is. Folks already drive up from Atlanta for sessions, and Nashville keeps coming up. Enough hands in the air in one city is what turns “maybe” into “when.” Tell me where you are, and I'll reach out when plans firm up.
