Gary A. Sippel —  President & FounderGaryIndividual2e

Gary founded AEI in 1977.   Equipped with a fleet comprised of a single backhoe, he was the sole employee of the company.  However, viewing the industry through a lens of possibility and with an eye toward the cutting-edge of excavating technology, his fleet and workforce did not stay that way for long.  By gradually adding members to his workforce and new machinery to his backhoe fleet, AEI evolved from doing small-scale sewer projects to becoming a residential site developer by the early 1980s.  This orientation toward possibility did not relent, and Gary continued expanding AEI into what it is today – a large scale commercial, industrial, and residential developer.
