The AON building is the big tall white building downtown.  There are several different entrances, when you get inside you can ask any of the staff where the visitor desk is to receive your guest pass.  You must be on the guest list to enter and present a photo ID.  If you have any issues call our office 800-323-1605.  Also make sure you get on the correct elevator to floor #51.  You can ask any of the nice building staff to assist you, if you have questions.

Our building is connected to the Pedway which is the underground walkway from the train station to the Aon building.  Our building has a Starbucks, Jimmy Johns and many other great restaurants, aside from all the incredible restaurants in the city, which you can google Chicago Steakhouse… to find something that meets your needs and price point.

Have a safe journey and we look forward to seeing you in the SDS HQ Office.
