In 2022, we announced that Cady Business Technologies acquired TSI, a leading telecom provider in Eau Claire, Wisconsin. Now, we’re excited to enter the next phase of the transition as TSI adopts the Cady name for a more cohesive customer experience.
As we complete the transition from TSI to Cady and honor this union, we have created an entirely new website to provide the best experience for all our customers across the country. You’ll receive the same white glove service you’ve come to expect from TSI—but with a broader pool of technical and customer service support and knowledge.
The two companies share a rich history, as TSI was originally co-founded by Duane Dingmann and Bob Cady. Bob Cady was the father of Dan Cady, who founded Cady Business Technologies. We also share core values rooted in exceptional service and a culture of excellence:
- Hard Work
- Critical Thinking
- Doing the Right Thing
- Teamwork
- Having Fun
- Constant Improvement
We appreciate every single one of you and are so excited for the future!
