History

It started with the dream of a Montana cowboy in the early 1900s … H. H. Henningson wanted to help small communities through civil engineering. Thanks to his persistence, the dream became reality in 1917 when he founded Henningson Engineering Company in Omaha.

More than 90 years later, the employee-owned firm has blossomed into one of the nation's largest and most respected architecture-engineering companies, employing more than 7,500 professionals in more than 165 locations worldwide.
