In special recognition of a century of excellence in construction, philanthropy, and economic contribution, the City of Chicago has officially proclaimed the year 2025 as the 100-Year Anniversary of W.E. O’Neil Construction.

The proclamation was made by Mayor Brandon Johnson during the City Council meeting on February 19, 2025, with attendance by John Russell (Regional President, Chicago and Texas) and other W.E. O’Neil employee-owners.

Founded in 1925 by William Edward O’Neil, W.E. O’Neil Construction has played a pivotal role in shaping the Chicago skyline and community. From local landmarks such as The Museum of Contemporary Art, Lane Tech High School, Crown Fountain at Millennium Park, restoration of the Chicago Theatre and the firm’s first project – The Primate House at Lincoln Park Zoo; to modern developments like Lincoln Common, Block 37, the University of Chicago’s William Eckhardt Research Center, and LondonHouse Hotel, our work has left an indelible mark on the city.

Beyond construction achievements, W.E. O’Neil has been a steadfast supporter of Chicago’s communities, contributing to organizations such as Habitat for Humanity, the Greater Chicago Food Depository, and Mercy Home for Boys and Girls.

“W.E. O’Neil Construction represents the very best of Chicago’s business and civic spirit,” said John. “For 100 years, our company has built not only structures but also stronger communities through our dedication to service, innovation, and philanthropy.”

As part of our centennial celebration, we will host events and initiatives throughout 2025, honoring our rich history and continued commitment to the City of Chicago.
