About Us

Jim Helleny started Jim’s Mobile Offices in 1986 as a company that provided construction trailers, mobile offices and storage containers to the construction industry. Early on in the business, Jim learned this simple truth – the best business plan is this:

  • Build a relationship with your customers.
  • Provide excellent products at a fair price.
  • Take care of your clients with outstanding customer service.

Along the way, Jim expanded the business to provide Relocatable Buildings as classrooms for schools throughout the Midwest as well as Permanent Modular Buildings for commercial applications. Over the years, we have provided modular space solutions to construction companies, schools, colleges, churches, hospitals, doctors, hotels, banks, golf courses, automobile dealers and many other businesses, as well as households. We have a large, specialized container fleet that can assist with any jobsite or residential storage issue.

Jim passed away in 2012, but his son Joe has taken over the leadership of the company, exercising those same values and respect for customers that were instilled in him by his father.  The company was rebranded in 2013 as JMO Mobile Modular, LLC, to better identify the changing role of the company while preserving homage to Jim’s vision.

Located in Southern Illinois, JMO Mobile Modular delivers permanent and relocatable modular and mobile buildings throughout the Midwest. We are proud to be long time members of the Modular Building Institute and the National Portable Storage Association.

Whether you need a storage container, a construction office, a relocatable classroom building, a new medical facility, bank, or any other type of modular building, be assured that JMO Mobile Modular approaches each opportunity with professionalism and a commitment to adhere to Jim’s core business plan – provide the customer with an excellent product at a fair price, and follow up with outstanding customer service.
