About HOH Group

Engineering Innovation, Continuing To Provide Exceptional Service

Since its founding, the HOH Group has been serving the needs of industry and government of Greater Chicago and of outlying states, and celebrates more than a half century of innovation and commerce. These segments evolved to include transportation, manufacturing, environment, process and construction management.

“We regarded 50 as middle age when you’re in the highest gear in terms of leadership and performance,” says Harry O. Hefter, chairman of the company. “Though in a world where many companies are swallowed by either merger or other happenstance, our longevity makes us a granddaddy in the engineering industry.” Indeed, HOH has been through much in its more than five decades. Four times it was selected by the National Society of Professional Engineers, (NSPE), as having one of the year’s “Ten Outstanding Engineering Achievements in the United States.”

In 1985, HOH was also selected as one of eight firms to represent the U.S. government on President Reagan’s Executive Trade Mission on Steelmaking to the Peoples Republic of China, the third leg of his technological exchange program.


HOH has proven its creativity by coupling it with cost effective engineering solutions to our clients’s operational needs. Capabilities in every aspect of engineering have forged HOH into the highly reliable resource that clients throughout the country depend on for difficult retrofit/upgrade projects, complex process design and for common sense on all issues. The following list is a sample of projects that HOH has successfully engineered:
