Career

Recognized as one of the most influential trial and arbitration lawyers in the United States, Terri Mascherin gets results. A Fellow of the prestigious American College of Trial Lawyers and a Co-Chair of the firm’s Litigation Department and Education Practice, she offers businesses, law firms, lawyers, and higher education institutions a full array of litigation tools to confront high-stakes challenges in court. She is equally adept at using alternative dispute resolution to address new or looming business threats and avoid litigation.

Businesses facing disputes involving corporate transactions, partnerships, and joint ventures are drawn to Terri’s reputation as a fierce advocate at trial and in arbitration. They soon find that her ability to pick the right battles is invaluable to their long-term success. In a highly nuanced matter, it’s Terri’s willingness to seek a favorable mediation or settlement over an all-out court victory that helps her clients’ business relationships stay intact.

When she’s not prosecuting and defending cases for clients in the financial, technology, media, energy, education, and legal industries, Terri puts the full force of her experience behind public service and pro bono matters. She served as president of the Chicago Bar Association and her pro bono practice focuses on criminal defense, securing justice for those wrongfully accused and convicted. Terri was instrumental in defending former Illinois Governor George Ryan’s clemency orders clearing death row for 167 prisoners.
