Every member of the Willis family is honored to be associated with such an architectural icon and privileged to call this prestigious business address our new Midwest Region headquarters,” Plumeri said. “Above all, the naming of Willis Tower is an affirmation of our strong commitment to the great city of Chicago, its people and its future. Willis has been in Chicago since 1885, the same year that William LeBaron Jenney built the Home Insurance Building, the first skyscraper in the world. Over the years, we’ve grown as Chicago has grown, and we are delighted to be a part of the great future this dynamic city is building as a global financial center. We’re proud to call Chicago our home.
