SEI was founded in Tecumseh, Michigan in 1995. Initially, SEI worked on small construction projects, pouring concrete and providing crane and rigging services in Southeast Michigan. Over the years, SEI has grown to serve Michigan, Ohio, and Indiana with a variety of self-perform services. In 1992, SEI moved its headquarters to Toledo, Ohio immediately adjacent to I-75 in order to better service its growing client list.
