Celebrating 70 Years
For 70 Years,
we've been compliant with the most demanding code of all:
Our Own.

Koorsen Fire & Security first opened for business in 1946. From the very beginning, we understood something important: we’re not just protecting buildings – we’re protecting the dreams that built them and the lives unfolding inside of them. Fire protection and security products are the tools of our trade, but people are the inspiration behind it.

So every day, we give our very best effort to the people who place their trust in us. And that’s how it’s been since we first opened 70 years ago. Over the years the technology we use has evolved, but the spirit that drives us hasn’t changed a bit.

Trust our people to protect your people.

Trust Our People to Protect Your People

It isn’t easy to become a certified Koorsen technician. We only accept the best candidates. And by the time we’re done with them, they’re true experts. That’s because every Koorsen technician is trained in our nationally acclaimed training center in Indianapolis. It’s a one-of-a-kind facility that incorporates both hands-on training and classroom learning.

What’s this mean for you? It means that when we’re on the job, you can trust it’s going to be done right.
