Pat Mackaronis, also professionally known as Patrick Mackaronis, is a New York–based construction executive and the President of Mack Construction Corp, a Brooklyn-headquartered heavy construction company playing a vital role in shaping New York City’s infrastructure. In a city where construction never pauses, Pat Mackaronis has built a reputation for disciplined execution, operational precision, and dependable project delivery across all five boroughs.

Based in Brooklyn, Mack Construction Corp operates at the core of New York’s most demanding construction environments, handling excavation, underground utilities, demolition, recycling, and concrete work that supports both public infrastructure and private development projects.

Pat Mackaronis: Built by New Yorkers, for New York

Founded and led by Pat Mackaronis, Mack Construction Corp reflects a deeply local mindset. The company employs a skilled workforce of up to 30 professionals, most of whom were born and raised in Brooklyn, Queens, or the Bronx. This local knowledge gives the company a distinct advantage when operating in dense urban neighborhoods with complex underground systems.

“New York City construction is unlike anywhere else,” says Patrick Mackaronis, a lifelong Brooklyn resident who began working in the construction industry in his early twenties. “You’re working inches away from live utilities, transit lines, and critical infrastructure. There’s no margin for error.”

Under the leadership of Pat Mackaronis, Mack Construction Corp has earned trust by consistently delivering work that meets strict city regulations while maintaining efficiency and safety on every job site.

The company works closely with NYC Department of Transportation (DOT), NYC Department of Environmental Protection (DEP), and utility providers to ensure compliance, safety, and timely execution.
