Willis Tower

Willis Tower, formerly Sears Tower, is the headquarters of Willis North America's Midwest Region. Standing at 1,450 feet and 110 stories high, Willis Tower is the tallest building in the Western Hemisphere. Willis currently occupies more than 140,000 square feet and three floors of the building.

Designed by the architectural firm Skidmore, Owings & Merrill for Sears, Roebuck & Company, the building was completed in 1973 and has since become one of the most recognizable landmarks in the Chicago skyline and in the world. More information on Willis Tower can be found at http://www.willistower.com/.

The building was renamed Willis Tower in July 2009 as the company consolidated five local offices and brought together some 500 Associates.
