Christine O’Reilly-Riordan

Christine O’Reilly-Riordan serves as Senior Vice President of Community Relations and Executive Director of Chicago White Sox Charities.

Under O’Reilly-Riordan’s stewardship, CWSC has donated more than $51 million to nonprofit and social service organizations across Chicagoland, strengthening programs that support youth, families, health and education. Her leadership of the organization’s Amateur City Elite (ACE) program helped earn Major League Baseball’s Allan H. Selig Award for Philanthropic Excellence in 2022, one of the league’s highest honors for community impact. The White Sox are one of just three major league clubs to be honored as two-time recipients of the special community-focused award.

O’Reilly-Riordan also was instrumental in the creation of the White Sox Volunteer Corps (established in 2009). Under her guidance, the fan-powered Corps has contributed in excess of 73,000 service hours to the greater Chicago community—labor valued at more than $1.8 million. It has engaged more than 15,000 White Sox fans over the course of 900+ service projects, including 120 in 2025 alone. The Volunteer Corps also was recognized with the 2011 MLB Commissioner’s Award for Philanthropic Excellence.
