Centennial
On May 21, our Chicago team hosted an unforgettable evening of celebration at The Langham Hotel overlooking the Chicago River to mark W.E. O’Neil’s 100th anniversary. Nearly 300 attendees gathered to commemorate a “Century of Building Dreams.“—a milestone made even more meaningful by the incredible people who joined us.
Guests were welcomed with champagne service right in the elevator, setting a festive tone from the start. The evening unfolded with lively networking over cocktails and hors d’oeuvres, accompanied by music from a band led by one of our very own Chicago team members—Jamal, a saxophone player with the group LovHertz.
We were honored to celebrate this milestone alongside so many friends, colleagues, and respected leaders from across Chicago’s development and commercial real estate community. The evening brought together a remarkable cross-section of the people who help shape our city—an inspiring reminder of the strong partnerships and shared vision that have fueled our work for the past century.
