It began in 1986 as Jim's Mobile Offices, a venture focused on mobile offices and containers for the construction industry, and it was rebranded in 2012 when Joe Helleny took over after his father’s passing. With a substantial container fleet and a Midwest service area, the company delivers turnkey modular projects with an emphasis on quality and service.

Its customer base spans construction firms, schools, churches, hospitals, hotels, banks, and other organizations, as well as households, reflecting a broad range of modular space needs.
