Kyle is a litigator who defends clients in complex commercial cases. He works closely with his clients to understand how they define success in each matter he handles and focuses on achieving that success in a strategic, efficient manner. Kyle is also the firm’s General Counsel. In that role, he is responsible for all legal matters for the firm, and counsels the firm’s lawyers and management on various legal and professional responsibility issues.

Kyle has a well-earned reputation for defending financial services firms. He has represented such firms in both class actions and individual suits in federal and state trial courts throughout the country in connection with securities fraud, market manipulation, qui tam, RICO, consumer fraud, and common law fraud claims. In addition, Kyle routinely defends broker-dealers in arbitrations before the Financial Industry Regulatory Authority (FINRA). He has defended major brokerage firms in FINRA arbitrations relating to investment products, including equities, auction rate securities, hedge funds and alternative investments. Kyle also represents such firms in connection with responding to regulatory investigations or inquiries.

Although he most frequently represents financial services firms, Kyle’s practice is industry-diverse. He has defended numerous securities fraud and consumer fraud class actions, as well as shareholder derivative, business tort, and contract cases for clients in the telecommunications, technology, media, and assisted living sectors.

Kyle also has extensive appellate experience. He has successfully argued before the Seventh Circuit Court of Appeals in a case that affirmed summary judgment in favor of a law firm facing allegations of legal malpractice, and the Second Circuit Court of Appeals in a case that affirmed summary judgment in favor of a major credit card bank.

Kyle is committed to serving pro bono clients. Sidley Austin LLP awarded Kyle the Thomas H. Morsch Award for Pro Bono Achievement in recognition of his successful representation of a Mauritanian refugee seeking political asylum in the United States. His other pro bono experience includes trying a breach of contract matter in Illinois state court and representing a criminal client in a postconviction appeal before the Seventh Circuit Court of Appeals. In 2023, Kyle was one of seven NGE attorneys to receive the Award for Excellence in Pro Bono Service from the U.S. District Court for the Northern District of Illinois and the Chicago Chapter of the Federal Bar Association.

Kyle serves on the board of Wonder Works, a nonprofit children’s museum in Oak Park. He is also an active member of the firm’s Diversity & Inclusion Committee, reflecting his commitment to fostering an inclusive environment both within and outside the firm.
