When you hear the name J. O'Neill Newark Ohio, you might think of a local Irish pub or a specific street corner. Honestly, it’s a bit of both, but mostly it's about the man who basically built the skyline—and the suburbs—of Licking County. Most people walk past the brick buildings in the Newark Arcade or drive through the industrial parks in Hebron without realizing that a single guy from Connecticut, who fell in love with a local girl in a Yale library, is the reason those places exist.
John J. "Jack" O'Neill wasn't just a developer. He was a visionary who saw cornfields and thought, "Yeah, a factory should go there." It’s kinda wild when you look back at how much one person influenced a mid-sized Ohio town.
The Man Behind the Name
Jack O'Neill landed in Ohio in 1953. He was a WWII vet with a BA in Economics and a wife, Betsy, whose roots were firmly planted in Granville. He didn't just come here to retire; he came to build. Starting the John J. O'Neill Building Company, he leaned into the post-war housing boom.
He started with prefabricated homes. Specifically, he worked with National Homes Corp to put up hundreds of houses for veterans. If you live in a mid-century ranch in Heath or Newark, there is a very high probability Jack O'Neill had something to do with the dirt it sits on.

It wasn't just houses, though. He moved into commercial real estate and eventually founded the Southgate Corporation. That name is still all over Newark and Heath today.
The Shift to Industrial Parks
By the late 1960s, Jack shifted his focus. He read an article about "industrial parks" in the Wall Street Journal—which apparently was his Bible—and decided Central Ohio needed one. He bought up land in Hebron and created the Newark Ohio Industrial Park (NOIP).
Think about this: that park eventually employed over 4,000 people.
It changed the economic DNA of the region.
The "Other" O'Neill: The Pub and the Legend
Here is where people get confused. If you search for "J. O'Neill Newark Ohio," you often get hits for O'Neill's Irish Pub. While the pub carries that classic Irish branding that fits the O'Neill name, the true "J. O'Neill" legacy in Newark is the development and the foundation.
The O'Neill Foundation is still a massive player in local philanthropy. They’ve poured money into:
- The Newark Arcade Project (bringing back that gorgeous historic glass-roofed shopping center).
- The STEM center at the local campus.
- Habitat for Humanity.
- Local band practice fields.
It’s not just about old money; it’s about active reinvestment. The foundation is run out of West Main Street in Newark and continues to be one of the quiet engines driving the city's "comeback" in the mid-2020s.

What Most People Get Wrong
People often think these big developers are just corporate entities. Jack O'Neill was the opposite. He used to "hold court" at the Bob Evans in Granville every single morning. He’d eat oatmeal and blueberries and let people pitch him ideas or ask for advice.
He was a Life Trustee at Denison University. He sat on the board of Park National Bank for decades. He wasn't some shadowy figure; he was the guy in the booth next to you.
Why it Still Matters in 2026
Newark is currently undergoing a massive revitalization. The Newark Arcade project, which the O'Neill Foundation heavily supported, is a centerpiece of the downtown's new look. When we talk about J. O'Neill in Newark, we aren't just talking about a dead developer. We’re talking about a blueprint for how a town survives the death of traditional manufacturing.
By building those industrial parks in the 70s, Jack O'Neill diversified the local economy long before "diversification" was a buzzword. He brought in companies that weren't just tied to one industry, which helped Newark stay afloat when other Rust Belt towns were sinking.
