For as long as I can remember, I was at my dad’s side.
His sidekick
I ran the machines, plowed through winter storms, rode along to estimates and ran errands with him. I was his sidekick, the way every son wants to be with his dad. If he ever did work for you, you probably knew who I was, because I was right there with him: at estimates, in meetings, at presentations and on the job.
Some of my favorite memories are the long nights during winter storms, when we’d watch Pink Panther together. Those nights are what bond me to this work and to this company.
Every time someone asked me as a kid what I wanted to be when I grew up, I gave the same answer: I wanted to work with my dad. At 7½ I even wrote it down on my “All About Me” page at school. I got that wish, but never the way I pictured it. I always thought we’d be doing it together.
How he raised us
My mom left when I was 12, and she passed away in August 2022. My dad raised us, and he did it while running his company. Watching him do both is why this work, and this company, mean everything to me.
What he taught me
What I carry from him most is his work ethic and his attention to detail. He taught me in ways I didn’t realize at the time. Looking back, everything he did was getting me ready for the day this would be mine.
Earning it
I went to Archbishop Williams High School, where I played Division 1 hockey and lacrosse in the Catholic Conference. By my senior year, I had customers of my own, and some of them are still with me today.
When I left for the University of Tampa to study finance, those customers didn’t find someone else. They waited for me to come home in the summer and at Thanksgiving to do their work. That kind of trust is what I’m building this company on.
Why I came home
When we lost my dad in April 2025, I was one semester from graduating, and I knew it was my time. My entire life, I watched him pour his blood, sweat and tears into this work. There was no way I was going to let that go unseen, so I came home and built J.A. DeMarco LLC to carry it forward.
I was 22, in a field full of men decades older than me. I had to prove myself on every job, and I still do.
Studying finance while running the company gave me the business side to go with the trade I grew up in. It feels like everything I’ve ever done led me exactly here, just without my dad beside me. It also taught me that I can do anything I put my mind to.
On every job, I ask myself what my dad would say if he were here. I can hear him the entire time I’m working.
Where we’re heading
We’ve grown from 50+ properties to 100+ residential and commercial properties across the South Shore. I graduate this December, and after that, this company gets all of me.
Over the next five years, I want to add electrical, plumbing and HVAC, so J.A. DeMarco LLC can be the one company you trust with everything at your house. Ten years from now, I want the people who watched us grow to be excited they were part of it.
What it means to me
My goal is to keep him remembered, to give him a voice through me, and to help others who are struggling. I believe that’s what God brought me here to do.
For our customers, it means you should always feel heard and always feel you can trust us. I want J.A. DeMarco LLC to be the name you trust with everything at your house: the lawn, the beds, the patio, the pest control and the snow. One call, one crew that knows your property, and every job done right, because our name is on the truck. Our own foremen run every job, we own our equipment, and when a job calls for a specialist, we bring in subcontractors we trust.
Most of all, I want my dad to be proud of me. That is my main goal.
