IT Infrastructure Operations
2024 - Present
In 2024, we expanded our IT infrastructure operations with the acquisition of a new facility just down the road from our Main Street campus, adding 7,000 square feet of dedicated operations space. This building now serves as the home of our Infrastructure Operations Division, enabling us to scale and enhance services such as security camera systems, door access control, and other physical wired technology solutions.
1001 - 1003 West Main Street Campus
2018 - Present
In 2018, to support our continued growth, we acquired our current Main Street campus and rebranded the company to better reflect our expanding range of services. Located in the heart of Sun Prairie, our campus now consists of two buildings totaling 5,400 square feet of office space—allowing us to operate more efficiently and deliver even greater value to the clients and communities we serve.
