IT Infrastructure Operations
2024 - Present
In 2024, we expanded our IT infrastructure capabilities with the acquisition of a new facility located just down the road from our Main Street campus. This addition provided 7,000 square feet of dedicated operations space, now home to our Infrastructure Operations Division. With this expansion, we’ve strengthened our ability to scale, streamline, and deliver advanced technology infrastructure solutions to better serve our clients.
1001 - 1003 West Main Street Campus
2018 - Present
In 2018, to support our continued growth, we acquired our Main Street campus and rebranded the company to better reflect our expanding range of services. Situated in the heart of Sun Prairie, the campus now includes two buildings with a combined 5,400 square feet of office space. This investment has enabled us to operate more efficiently, expand our capabilities, and deliver even greater value to the clients and communities we serve.
Bird and Main St Location
2015 - 2018
After outgrowing our previous location, we relocated just down the road to the corner of Bird and Main, where we operated out of a 2,200+ square foot retail and office space to support our growing team and expanding services.
Sun Prairie Location
2010 - 2015
We moved to the Sun Prairie area and opened shop right on main street with just over 900 Sq ft of Retail Space.
West Madison Location
2006 - 2010
Horstman Computers started in 2006 in the west town office center on Madison's west side with one goal in mind: to provide Madison and the surrounding areas with extraordinary technology support at an affordable price.
