About Tower Systems INC
From towersystems.com

Founded in 1975 to promote the TS Elevator Systems developed by company founder, Bill Carlson, Tower Systems has grown steadily over the years operating on the corporate values of safety, integrity, and exceptional customer service. The company quickly evolved into the telecommunications space, building towers all across the world. In 1991 Tower Systems moved its headquarters from Cambridge, Minnesota to Watertown, South Dakota, taking advantage of South Dakota’s favorable business climate. Two years later, with the cellular boom in full force, the Southeast division was added in Winter Park, Florida. And in 1997, always staying loyal to his hometown roots, Bill added a satellite office in Angle Inlet, Minnesota which allowed him to work, fish, hunt, and enjoy his family all at the same time. Today, the company is led by Bill’s daughter Kari and is proud to hold the designation of Woman-Owned Business. Kari and the Tower Systems team continue to enlarge its global footprint while maintaining the values that it was founded upon over 45 years ago.

What Tower Systems INC is registered to do
