About TSR Solutions
Founded in 1991, TSR Solutions has been helping businesses leverage technology with purpose for over three decades.
Our Story
TSR Solutions was founded in 1991 by Tim Radtke with a simple philosophy: "Technology on Purpose." What started as a small IT consulting firm in Waukesha, Wisconsin, has grown into a full-service managed IT provider serving businesses across the Midwest.
For over 30 years, we've evolved alongside the technology landscape — from the early days of networking and server administration to today's complex world of cloud computing, cybersecurity, and digital transformation. Through it all, our commitment has remained the same: deliver technology solutions that serve a clear business purpose.
Today, TSR Solutions employs a team of certified IT professionals across six offices in Wisconsin, Illinois, and Minnesota. We serve hundreds of businesses ranging from small professional firms to mid-market enterprises, all with the same personalized attention and proactive approach that has defined our company since day one.
