Brenna Berman, Commissioner & CIO

Chicago Department of Innovation and Technology (DoIT) Commissioner and CIO, Brenna Berman joined the Emanuel administration in 2011 as Deputy Budget Director focused on enterprise initiatives and performance management. After a year in that role, Brenna transitioned to DoIT as First Deputy Commissioner to focus on enterprise IT consolidation and operational excellence. Since joining DoIT, Berman has focused on transforming the team to align with the Mayor’s commitment to an open and data-driven government, building Chicago’s open data program into one of the largest in the country, implemented the ground-breaking “WindyGrid” spatial analytics platform into every level of government, integrating advanced analytics and real-time data-driven decision making across the city, and setting a new standard for government IT.

Berman played a critical role in transforming the team at DoIT to provide the skills and expertise to implement the Mayor’s commitment to leveraging data and technology to create a more efficient, effective and innovative City government. This has meant adding new skills to the team to increase the focus on software engineering and analytics, improving the department’s commercial partnerships to drive savings for the City and identifying ground-breaking civic partnerships, including hosting regular meetings with local female tech startup owners.

Berman built a career promoting government innovation during over 10 years at IBM, where she worked closely with government agencies in cities and countries across the world to leverage technology and analytics to improve the services they provide to their residents. Berman advised governments on a variety of issues, from targeting personalized services through analytics to normalizing program offerings to simplify the delivery process and make them understandable to residents. Throughout her time at IBM, Berman tailored cutting-edge business and data models, from processes to analytic algorithms for large government organizations in order to accelerate their own modernization efforts, providing an incredibly valuable skill set for the work she continues at DoIT.

Brenna earned her bachelor’s degree and Masters in Public Policy from the University of Chicago. She resides in Chicago with her husband and two sons.
