Our proudest accomplishment is our people. We hire team members who share beliefs in family, safety, partnership, and process improvement. Our culture is one of trust and personal responsibility dedicated to empowering and growing employees for years to come.
WE’VE MADE IT OUR MISSION
to identify, hire, train, and retain the best people to serve our customers.
In Five Generations
We’ve grown into a $500+ million, full-service construction company with over 650 employees. Much has changed since then, but one thing has stayed the same:
Our clients can always rely on us to get the job done on time and at the highest quality.
John Patrick Cullen, our founder, set an example for his employees that we still live by today: Deliver the best product to the customer, and conduct yourself with the utmost integrity and trustworthiness. We carry his legacy forward by continuously improving every process we perform—and working smarter and harder than any other construction company in our region.

The different opportunities within JP Cullen are vast, also the family style reputation the company has and continually reinforces day to day are a great culture to be a part of.
As I child I remember seeing Cullen operations in downtown Madison & Milwaukee building some of the most iconic buildings in the State. Of course, I wanted to come work for a contractor that works on Camp Randall, Buck’s Stadium, Miller Park, State Capital & Milwaukee City Hall. Who wouldn’t want to come work for the best?
I knew after meeting with some of the employees who have been here for many years that JP Cullen took pride in growing their employee’s careers and finding the right place for an employee within the company.
How it all started
In 1892, John Patrick (or J. P.) Cullen founded J. P. Cullen & Sons Construction in Janesville, Wisconsin, about 50 miles southeast of Madison.
In 1892, John Patrick (J.P.) Cullen founded a construction company in Janesville, Wisconsin, and builds his first project. The era when a wheelbarrow could be purchased for 95 cents and a ball of twine costs five cents at the local hardware store.
Being a respectable contractor and business owner, he was a great catch for any young lady. It wasn’t long before he fell in love, his heart snared by another Irish émigré, Alice Rooney. They married November 24, 1892, a mere four years after meeting. The two go on to have four children, earmarking the beginning of the succession of the now fifth generation of ownership.
Building Our Communities
Our dedication to personal development, family and community is in our blood and at the core of our business.
