Now that’s a crane. 👀🏗️ A 770-ton crane was recently onsite at one of our major food and beverage clients, helping our team remove 16 semi loads of material. Just another example of the planning and coordination that goes into getting big work done safely and efficiently.

Janesville has a story worth celebrating!

Last week, our team joined hundreds of local businesses and community leaders for the Forward Janesville Inc Annual Dinner. George Cullen had the opportunity to share a bit of Janesville’s story and reflect on its history as part of an evening focused on the community’s past, present and future. Thanks to Forward Janesville for a great night!

Nearly 20 years ago, we helped lay the foundation for the Wisconsin Institutes for Medical Research, completing masonry and concrete work for the building. Today, we’re back at that very foundation as part of the team bringing its next chapter to life: an expansion of UW–Madison’s cyclotron lab. The project will help advance research into targeted cancer treatments and expand what’s possible for patients right here in Wisconsin.

A couple of years after opening, we’re looking back at what it took to bring UW Health ’s Eastpark Medical Center to life and expand access to specialized care, advanced cancer treatment, and clinical research across the region.

Behind the 475,000+ square-foot, seven-story facility was a 28-month build involving more than 40 specialty services, a 73-chair infusion center and one of the project’s most complex components: the proton therapy treatment area, which began seeing patients earlier this year. From specialized foundations and mass concrete placements to planning for future upright proton therapy capabilities, every piece required careful coordination between UW Health, our joint venture partner Mortenson , designers and trade partners.

The result is more than a new healthcare facility. Completed in 2024 as the largest medical facility finished in the United States that year, Eastpark was built to support patients, evolving technology and the future of healthcare in Wisconsin.

A little friendly competition for a great cause! 🩸❤️ Our recent blood drive with Westphal & Co had an incredible turnout, helping cap off a great year of giving. Thanks to everyone who rolled up their sleeves throughout the year, we finished 27% above our annual blood donation goal!

A huge thank you to our JP Cullen team members, our friends at Westphal, and everyone who donated. Every donation makes a difference!

No tricks, all treats! 🎃 This past weekend, we joined Make-A-Wish Wisconsin for its 2nd annual Trunk or Treat event. Of course, our team had to stay on theme with a mini construction site for kids to check out while grabbing some candy.

Wishing everyone a safe and fun Halloween over the next couple of weeks!

Shout out to Kevin, Sarah, Jaime and Colleen for joining the fun this year!
