Jennifer (Jen) Aronoff focuses her practice on civil and criminal government enforcement actions, internal investigations, and complex commercial litigation. A former journalist, Jen uses her experience at gathering and deploying facts to help tell clients’ stories, and she has helped clients succeed at both the trial and appellate levels through clear and persuasive written and oral advocacy and keen legal analysis. Jen is also versed in advising clients on compliance questions.
Jen has drafted a range of winning dispositive motions and appellate briefs in both state and federal court, aided by her knowledge of jurisdiction, civil procedure, and administrative law. She represents and counsels clients in matters involving the False Claims Act, federal securities and healthcare law, and the Foreign Corrupt Practices Act, among other areas, as well as commercial disputes. She also advises clients on and manages responses to civil investigative demands and government subpoenas.
Jen has an active pro bono practice and received the 2018 McDermott Will & Emery Award for Outstanding Achievement and Commitment to Pro Bono and Service to the Community. Jen was part of a McDermott team that successfully defended a pharmacist charged with racketeering, racketeering conspiracy, mail fraud, and federal Food, Drug and Cosmetic Act violations, winning a full acquittal following a two-month federal jury trial. Following work as a law student in Northwestern University’s Center on Wrongful Convictions of Youth (CWCY), she also serves clients in matters involving juvenile justice and challenges to wrongful convictions. During her time with the CWCY, Jen was part of a team that helped free a man who had been wrongfully convicted of murder as a teenager. The team established that the state had ignored the true perpetrator and failed to disclose favorable evidence to the defense. In addition, Jen obtained a favorable settlement for a client in a federal civil rights case and has assisted on briefing in pro bono Seventh Circuit criminal appeals.
Previously, Jen served as law clerk to the Honorable Thomas M. Hardiman of the U.S. Court of Appeals for the Third Circuit.
