What if your next construction project ran smoother—start to finish?
Graham Health System didn’t just need a roofing contractor. They needed a long-term partner—someone who knew their facilities, worked within their budget, and took ownership from day one. That’s what they found in Holthaus Roofing.
Hear from Bob Sennett, CEO of Graham Health System, on why Holthaus Roofing has been their go-to partner for nearly two decades.
Imagine if your roofer handled it—before you had to ask.
What if roofing wasn’t something you had to chase, question, or manage? For healthcare leaders like you, every minute matters. Here’s what working with a partner like Holthaus can look like:
Without a Roofing Partner
Bid juggling & budget surprises
Projects dragging past deadlines
Unfamiliar crews each time
Fix-it-when-it-breaks mindset
With Holthaus Roofing
One clear number—no surprises
Delivered on time, with less stress
A team who knows your facility
Proactive care & smart planning

What long-term trust looks like.
Graham Health System in Canton, Illinois, has completed over $120 million in construction projects across the last 20 years. And every time it involved a roof, they’ve relied on Holthaus Roofing.
Why? Because when they hand us a project, they know it’ll get done right—on time, on budget, and without headaches.
“We’ve worked with Holthaus on every major project.”
