Three Decades of IT Expertise for the Materials Industry
Centrix Systems isn't a generic IT company that happened to land a concrete client. We were built from the ground up to serve producers like you.
Meet Bill Callahan Jr., Founder & CEO
In 1994, Bill Callahan Jr. saw something that most IT providers missed: the construction materials industry was becoming increasingly dependent on technology, but nobody was building IT services around its unique needs. Dispatch systems, batch controllers, scale house computers, and plant networks all required specialized knowledge that generic managed service providers simply didn't have.
Bill founded Centrix Systems to fill that gap. With deep roots in the ready-mix concrete world, he assembled a team that could walk a plant floor, troubleshoot Command Alkon, configure Trimble systems, and design networks that survived dust, heat, and vibration—all while speaking the language of producers, not just technicians.
Today, Bill continues to lead Centrix with the same founding principle: technology should serve production, not the other way around. Every service we offer—from managed IT to cybersecurity—is shaped by decades of hands-on experience in the materials industry.
