Caitlyn Brennan

A Class of 2002 Sandburg High School graduate, Caitlyn Brennan has a passion for serving others. After receiving her bachelor’s degree from Miami University with a triple major in History, Sociology, and Religion, she moved to South Africa to intern with the U.S. State Department, shadowing Foreign Service Officers during their work on the AIDS pandemic. Returning stateside, Caitlyn obtained her master’s degree in Public Service Management and spent much of her time traveling the world implementing emergency management and sustainability measures. In 2013, she came upon The 100 Club of Chicago, a nonprofit that provided support to families of first responders who were killed in the line of duty in Cook County. She stayed with this mission, taking on various titles, until 2020 when she became the Chief Executive Officer. She broadened the mission of the Club to include every county of the State. She now runs the 100 Club of Illinois serving all 102 counties and roughly 80,000 first responders.
