  • Crowell & Moring’s Chicago office has deep midwestern roots and a long-standing commitment to the surrounding community. We partner with local legal aid agencies on a number of fronts, including: assisting residents in housing court that are facing improper evictions; acting as court-appointed guardians to represent the interests of minors; and providing legal advice to artists and art organizations.

    We are also active in local pipeline development initiatives. Since the founding of Legal Prep in 2012, the Chicago office has supported Legal Prep Charter Academies. Legal Prep is a free, open-enrollment high school with mostly Black students that was founded to inspire young people and increase the diversity of the legal profession and judiciary. Every year, our attorneys volunteer to teach Legal Prep’s high school students in a mock trial course, which provides several benefits to students, including improving their written and oral communication, critical thinking, problem solving, and advocacy skills. Through this immersive exercise, Crowell volunteers guide students to a deeper understanding of the various stages that make up a trial.
