You probably know SIOP has about 10,000 members, but do you know how many volunteers support the work of the Society? Every year, it’s close to 1,000!
In order to recognize our Committee volunteers, we’re hosting the SIOP Commons as a Thank You for your efforts during the year
Located in the Exhibit Hall of the Riverside Center of the Hyatt Regency Chicago’s East Tower, you will find inviting seating and a cushioned floor where you can meet with colleagues – some of whom you may have never met in-person before!

The SIOP Commons will be open
Thursday April 3, 2025, 8-11:30 a.m. and 1-6 p.m. MST
Friday April 4, 2025, 8-11:30 a.m. and 1-5 p.m. MST
The Membership Committee will be present for all open hours of the event, to answer any and all membership questions.
