// JANUARY 1, 2009

My Story

New Year's Day, 2009. I was twenty years old, standing in front of a detox door with everything I owned in a duffel bag.

Not a figure of speech. One bag. I had spent four and a half years taking my own life apart, and that morning the entire inventory of what was left fit on one shoulder.

I walked through the door. I have been clean since the first minute of that day — the first minute of January 1, 2009 — and I count it from the minute on purpose. That minute is the hinge everything else in my life swings on.

To explain how I got to that door, I have to go back.

// THE KID

Ironed money

I grew up in North Haven, Connecticut. Bikes in the street, a Nintendo 64 in a friend's garage, and a brain that was always hunting for the next thing to feel.

I ironed my money. Whatever I managed to save, I pressed the bills flat with an iron and kept them in a careful stack. I valued them so much I wanted them to look like they meant something. Some things don't change.

At eight, I built a Lego battleship from scratch on a six-foot folding table in my bedroom. No kit. No instructions. When it was done I took it apart and built something else. I took apart anything I could get my hands on, just to see how it worked.

School was the opposite. I hated it — not in the softened “I learn differently” way people say now. I genuinely hated it. So I engineered my grades: not failing, not good, mediocre with precision, tuned so no teacher would ever call on me. It worked. My GPA was a 1.6. I never took the SATs. Nobody wondered whether I was going to college.

I heard “no” a lot as a kid. Mostly I treated it as a starting point.

// THE FALL

Four and a half years

I was fourteen when I started selling drugs. It wasn't about the money. I identified a demand, so I found a supply — it kept my own costs low, and I liked how it felt to be the connect. The guy everybody called. Demand, supply, being the one who delivers: the same wiring that runs my company today, pointed at the worst possible market.

I was sixteen the first time I used opiates. I'm not going to dress that up, and I'm not going to make it darker than it was. The truth — the part nobody wants to say out loud — is that it felt like a key turning in a lock. A brain that never once sat still, sat still.

That feeling doesn't come free. It cost me four and a half years.

Opiates. Cocaine. Whatever was available. There's no montage for those years and I'm not going to write one, because addiction isn't cinematic — it's boring. The same day on repeat, each one slightly worse than the last. The money I used to iron went. The trust went. The people went. So did the jobs: an HVAC company fired me, and the Dairy Queen I landed at after that — my last job before detox — fired me too. By twenty, everything I owned fit in a duffel bag, and you already know where the bag ends up.

The full version of those years belongs to the memoir, and I'm writing it. What matters for this page is how it ended: I walked into that detox on New Year's Day and I never walked back out into the old life.

// THE RESTART

Nothing

After detox came a sober house in Westerly, Rhode Island. Four months.

I want to be precise here, because “started over with nothing” gets used as a figure of speech. This was not a figure of speech. Nothing is a specific, terrifying amount to own. I was twenty years old, clean for the first time since I was fourteen, fired from every job I'd ever had — and every single thing my life was going to contain, I had not built yet.

There is a strange freedom on the far side of that. When you own nothing, nothing owns you back. Nobody expected a thing from me — which meant every expectation I met from then on was one I had set myself.

// THE DIAGNOSIS

The prescription I never filled

A few months after I got clean, a psychiatrist diagnosed me with ADHD.

He explained dopamine dysregulation. Prefrontal cortex underactivation. Why my brain idled rough and revved clean. Why opiates had felt like a key turning in a lock — because for a brain wired like mine, chemically, they almost were.

Then he handed me a prescription.

I never filled it. I still haven't. I had just spent four and a half years learning what happens when I outsource how I feel to a substance, and I wasn't going to open the new life by doing it again with a co-signature. I'm not a doctor, and plenty of people do well on medication — this was a line I drew for myself, not advice for you. But I drew it, and I've held it.

What I did instead was file away everything he told me and start building a system — the one I still run today. That system lives at The Brain, because it deserves its own page.

I didn't fix myself. I aimed myself.

// THE EMPTY DESK

The desk nobody gave me

I found a small company and I showed up. I made myself useful. I learned everything anyone there would teach me, and when I ran out of things to be taught, I found an empty desk and sat down at it.

Nobody assigned me that desk. I didn't ask. I just started doing the work I thought the desk should be doing. Eventually somebody brought me a docking station. Then monitors. And after I had done the job long enough that not giving it to me got awkward, they gave me the title: product manager.

The desk happened to sit in the precision calibration world — test equipment, tolerances, certificates — and I went deep. I traveled. I sold. I managed. I had engineered a 1.6 GPA so nobody would call on me. Now I was the guy people called first.

That desk is still the most important piece of furniture in my life. You don't need a plan or a pedigree or anyone's permission. You just need to find the desk. And sit down.

// THE BUSINESS

A failing lab in my hometown

In 2019 I took over a failing calibration lab in North Haven — the same town I grew up in — and started building Custom Calibration out of what was left of it.

Today Custom Calibration does about $1.3 million a year. I have employees who count on me, which is a sentence I don't write casually — there was a version of me nobody would have trusted with a twenty-dollar bill. I work on the business now, not just in it, and I'm building toward one of the largest calibration labs in the Northeast.

How that actually works — the numbers, the decisions, the software I'm building to run it — lives at The Business.

// NOW

Where I am, exactly

I married Rosanna — four-foot-eleven, talks constantly, best decision I ever made. We have two daughters: one who overthinks everything exactly the way I do, and one who is so stubborn she won't put her shoes on before school and is going to be completely unstoppable because of it.

My days start at 5am. My spice drawer is organized with a precision most people find slightly alarming. I 3D-print custom Tupperware organizers. I wear an Oura ring and check it obsessively. Ketogenic diet, eighteen-hour fasts, training every day, about twenty grams of creatine — for the brain, not the biceps.

And right now I'm twelve pounds over my baseline. I came home from a vacation with my Italian relatives heavier and off the protocol, and I'm restarting it — in public, on this site. I'm telling you that on the same page where I tell you everything else because the restart is the whole point. I've restarted more times than I can count. The restart is the skill.

Here's where this goes, stated plainly, because I'd rather say it than make you decode it: I want to acquire companies. I want to grow Custom Calibration and eventually sell it. I want to launch new ones. I'm writing two books along the way — the story and the system — and I'm doing all of it out loud, one honest post a week.

I'm thirty-eight years old. I have been clean since the first minute of January 1, 2009. I'm enjoying every second of it.

// SPEAKING & MEDIA

I talk about this stuff on stages and podcasts.

The addiction, the ADHD, the business built out of a duffel bag — I tell it the same way in a room as I do on this page. If you want me on yours, these are the talks I give:

  • Building without credentials: what I've done with a 1.6 GPA and no degree, and what ADHD founders do differently
  • The protocol: how I run an ADHD brain without medication — mornings, fasting, creatine, tracking
  • Recovery as an edge: what losing everything at twenty taught me about building
  • The wiring: why the traits everyone calls your problems might be the best tools you have
