Our Story

The Spartan IT Group was founded by Marc Petersen in 2014, with roots in the technology world originating during the early years of commercial internet and Windows computers. Our mission from inception was to create a forward-thinking IT firm with pristine attention to detail and a focus on the success of our clients. With this purpose in mind, TSG has continued to support and uplift many of Indiana’s most respected companies. Our mission now is simple. We want to redefine the concept of work using technology.

Our Mission

Work is part of the human experience but sadly it is still inefficient and filled with unnecessary frustrations. Today we have the technology to change the concept of work forever for the better. Our platform uses technology and strategy to redefine work. Join us as we improve the life experience of every company and individual, we interact with.
