What Our
Clients Say

“Prairie Signs is our go to vendor for installing and maintaining digital and static billboards for Picture This Outdoor Advertising. This particular project, they installed some upgrades. Although we had a few bumps with the parts supplier, Prairie's staff was great. The service tech was both patient and persistent to get the job done, kept in touch as the job progressed and made a tough day a little easier with his positive attitude - even 20 feet up in the air on a cold December day.”
