Nearly four decades of craftsmanship. One uncompromising standard.
Deerfield Interiors is led by Marc Piacenti — a master craftsman who started his first millwork company as a teenager and has served the tri-state area — New York, New Jersey, and Connecticut, including all of Long Island — since 1990. Every project that leaves our Deer Park shop is inspected by his team of experts and professionals — the joint, the finish, and the install.
His first millwork company, at seventeen
Marc Piacenti started his first millwork company at seventeen years old. He called it MICA BY MARC, and he ran it the way he still runs a shop today: with a saw in his hands and his name on the work. While most kids his age were figuring out what they wanted to do, Marc was already building real, finished millwork and handing it to paying clients.
The work clicked fast. Marc didn't just want it built — he wanted it built right. Every mitered corner had to read as a single line of grain. Every cabinet door had to swing dead-true. That instinct for tight tolerances and clean finish, formed as a teenage entrepreneur, is the foundation everything else was built on.
MICA BY MARC was the seed. Over the decades that scrappy one-man operation grew into a full commercial shop — the same craft, the same standard, the same hands, evolving step by step into what is now Deerfield Interiors.
The shop grows up — and word travels fast
By 1999, the business Marc had started as a teenager had outgrown its first name. He incorporated as Highland Organization Corp at 435 Brook Avenue in Deer Park — a bigger shop and a tight crew, with the same phone book full of contractors who needed millwork done the right way.
Word spread quickly. Marc didn't sell — the work did. Dental practices, medical offices, banking interiors, retail buildouts. General contractors began calling Highland first because Marc's installs came in on time, dead-on spec, and didn't generate punch-list headaches. The shop grew. The crew grew. The reputation locked in.
By the mid-2000s, Highland had become one of the most respected millwork shops in the tri-state area — a thirty-five-person operation with multi-million dollar annual volume and a project list spanning New York City, Long Island, New Jersey, and Connecticut. Marc was running the company the same way he ran his bench: hands-on, eyes on every detail, refusing to ship anything that didn't pass his standard.

After two decades of running Highland across every conceivable trade — millwork, finish carpentry, tile, design coordination — Marc made a decision: focus. Strip the operation back to what he was always the best at, and build a brand around that one thing. Commercial millwork. Built right.
That focus became Deerfield Interiors. Same shop. Same address. Same crew. Same standards. But now every project that leaves Deer Park is millwork-specific — cabinetry, casework, moldings, reception desks, built-ins — built to AWI-certified standards. From a seventeen-year-old's first company to an AWI-certified shop that has served the tri-state area since 1990 — New York City, Long Island, New Jersey, and Connecticut — the entire operation is pointed at one craft, executed at the highest level.
Hands-on. Detail-obsessed. Team-driven.
“If it isn't right, it doesn't ship. That's the only rule.”
Marc leads from the front. Nearly four decades in, he has built a team of craftsmen who look at every project the way he does — inspecting the measure-up, the rough-in, and the install with the same critical eye he honed at the bench. Every single time.
Clients describe him the same way: laser-focused. He'll spec a wood grain direction down to the panel. He'll fly out to a jobsite at six in the morning because the install crew has a question. That kind of attention is rare in commercial construction — and it's why Deerfield projects come in clean, on time, and with finishes that make architects look good.
The crew Marc has built has been with him for years — seasoned project managers, draftsmen, and installers. Not subcontractors, not rotating labor, but professionals who know the Deerfield standard by heart. That continuity is why Deerfield can promise the same quality every time.
When you call Deerfield, you get a team that works with integrity under one standard — the Deerfield standard. They show up. They deliver. There's no project too detailed, no client too demanding. If millwork is what you need built — and built right — this is the team you want building it.
