Employee Check-In
Then & Now
Meet Tom
Tom Pertzborn, Senior Project Manager with our Healthcare Division, has been with JP Cullen since 1996 starting as an intern:
“Many things have changed since I started with JP Cullen. Fax Machines were the modern technology, my first cell phone looked like I was calling in an air strike, and JP Cullen was not even half the size we are today.
I started with a group of 6 interns which was the largest amount of interns JP Cullen had hired prior to that time.
Over the last 20 some years I have been lucky enough to work with three generations of Cullen’s.”

Well I’ve been with JP Cullen for 20+ years, the company has changed a lot since I started. One of the big things that I like about JP Cullen is the family atmosphere. The opportunities that they have given to me have help me grow as a person. For anyone interested in a career in the company go for it and see where it leads you.

When I was looking to make a career change I was looking for a company to join that was family focused where I could work hard, make a difference in my community and not be seen as just another cog in the wheel. For as long as I can remember JP Cullen has been known as a family-owned company full of hard working people that gives back to the communities they serve, so when the opportunity to join JP Cullen arose, I jumped and haven’t looked back!

My first impressions of JP Cullen came from their presence at UW-Madison. The work they performed while I was a student and continue to do now on campus always stands out. Now I have had the opportunity to travel for projects nation-wide, which provides its own unique sets of challenges. The range of JP Cullen is truly remarkable.

One reason I like my job is the people I work with. I’ve worked with a lot of project teams over the years and interacting with people in the field has always been one of my favorite parts of the job.

Project Coordinator
JP Cullen
My first project with Cullen was a production line changeover at General Motors in Janesville – and there aren’t many projects tougher than a fast-paced Industrial shutdown. I really enjoyed the challenges of that project and those that have followed. I’ve been with Cullen for 16 years now.
