JP Cullen

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?

How it all started

Our History

In 1892, John Patrick (or J. P.) Cullen founded J. P. Cullen & Sons Construction in Janesville, Wisconsin, about 50 miles southeast of Madison.

1900

1892

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.

1892

1925

1900

In the early 1900’s J.P. finds solid work in the Education and Civic markets. He bid on and won his first civic job – a two-story brick school in Palmyra. The architect later put out 22 pages of intensive specifications which included “good, hard, and well burned” brick walls. Since the Cullens had the art for brickwork, that would not be a problem – it’s in the genes. Later, he signs on with two brothers to build the Red-Brick Armory block of Downtown Janesville and installed newfangled contraptions called elevators, making it the talk of the town.

On April 16, 1904, Janesville’s laborers form a construction trades union, at that time J.P. recalls starting the business as an apprentice laborer and agrees to make the Cullen firm a union shop, which it remains to this day.

1900

1933

1925

His son, Mark, leaves University to serve in the Army. When Mark returns from his service in 1918, he joins his father in the family business. He quickly works his way up the ranks and marries longtime Janesville sweetheart, Beatrice Field and a year after welcome their first child, John Paul Cullen. Quickly becoming another J.P. much to his grandfather’s delight. They then move to Madison where Mark is Superintendent for several jobs, including an addition to University of Wisconsin’s Bascom Hall. The job that opens the way for the next three generations of Cullens to help shape physical face of the State Capitol and the University.

1925

1959

1933

Business continues to prosper throughout the depression. Federal buildings and post offices around the Midwest are key to Cullen’s success. Mark A. builds a new house on Garfield Avenue in Janesville, still owned by his grandson, the next Mark, today.

In 1936 Mark A. is stricken with tuberculosis and confined to a sanatorium for nine months. During Mark’s protracted recovery, son J.P. joins the military shortly after turning 18. Then goes on to tour France, Germany, Czechoslovakia, Austria, and the Philippines. Upon his return home he seeks secondary education. Shortly after his graduation J.P. is called to Janesville to help run the family firm at the current Janesville Headquarters on Delavan Drive.

1933

1975

1959

J.P. gets married and starts a family. By this time, J.P. is de facto boss of the company. Mark A.’s health was failing due to a relapse of tuberculosis. But he was always available to answer questions and consult on projects. His motto was that there are no dumb questions, as a result, he was always willing to assist. Although eventually retiring from the company’s daily routine, Mark A. remains active in the back office until his death in 1970 at age 74. He is remembered as a good businessman and classy fellow.

Meanwhile, J.P.’s sons – Mark, David and Richard – know their way around the company yard by the time they can pick up a hammer. Their sister, Sarah, spared these tasks. J.P. does not push any of his kids into the family business but leaves the door invitingly wide open.

1959

2000

1975

Milwaukee Pro Sports and Service, a public company that owned the Milwaukee Bucks, sells their stocks to a Janesville group for $8 per share. J.P. is part of the ownership group that took the team and controlled the franchise for about 10 years, with the Bucks winning the Division Title six years in a row and regularly making the playoffs. They sold the team in 1985 for $94 per share.

Mark, David, and Richard eventually join J.P. at the family business. They soon learn Cullen is a company of “regular people,” observing their parents opening their home for Christmas parties and going to office get-togethers that bring the staff together, mingling truck drivers with supervisors.

In March of 1999, JP Cullen opens its first branch office in Milwaukee. One of this office’s signature projects is the historic renovation of Milwaukee’s City Hall.

1975

2015

2000

As the century comes to a close, the company grows to nearly 450 employees. JP Cullen restores the glory of Wisconsin’s most significant building, The State Capitol. This complex project spans 10 years.

Working with General Motors for more than fifty years, JP Cullen had completed three million square feet in additions and maintenance. This was key to the growth of the company, specifically the Industrial Division. The newly formed division found its Vice President and leader, the late, Ron Becher, and becomes the fastest growing market segment for the company.

2000

2020

2015

In 2015, JP Cullen wins the Associated General Contractors of America’s Alliant Build America Grand Award for Epic’s Deep Space Auditorium. Epic has been a client for 20 years. In June of 2015, the Downtown Madison branch office opens just as 306 West Main Apartments and The Henry Vilas Zoo’s Artic Passage projects are completed.

In 2018, the Milwaukee Division office relocates to the downtown Fortress Building to align with the company’s mission to identify, hire, train, and retain the best people to serve our customers. Prior to the move, our talented tradespeople renovated the entire historic building, transforming the abandoned shoe factory to our new office as well as apartments and retail spaces.

2015

2020

JP Cullen completes multiple projects with the Milwaukee Bucks including the Sports Science Center, McKinley Health Center, eSports League Space & structure steel for the Fiserv Forum.

Late 2020, Jeannie & George are named Co-Presidents of the company. The pair replace the late Ron Becher, the only non-Cullen who led the company, for more than six years. Their selection brings forward the fifth generation of the Cullen family, which is quite an accomplishment considering that only about 3% of family businesses survive into the fourth generation or beyond.

In 2022 the fifth generation become owners. Having Jeannie, George, Dan, Laura and Sean involved as leaders brings added value to the firm’s culture. Each member of this generation agrees that they must be as pioneering as all the Cullens who precede them, and at the same time they must care for their community and people.
