Charlie is a commercial litigator who represents plaintiffs and defendants in all phases of complex civil litigation, from pre-suit strategic development through trial and appeal. He has particular experience with healthcare fraud claims (e.g., involving drug pricing and payor reimbursement), corporate governance and deal litigation (e.g., fiduciary duty claims or disputes over indemnification, shareholder equity or control rights, or incentive-equity repurchases), commercial contract disputes (e.g., breach or restrictive-covenant claims), and securities fraud class actions. But his broad practice covers many types of civil litigation in federal and state courts across the country.

Charlie’s clients include healthcare, life-sciences, and technology companies, private equity firms and their portfolio companies, asset managers and financial services companies, and their principals. Those clients especially value Charlie’s sophisticated, creative litigation strategies; his ability to accurately anticipate developments and predict likely outcomes; his well-reasoned, practical advice; his strong advocacy and communication skills; and his service-oriented mindset.

Charlie also maintains an active pro bono practice, representing low-income clients in class action litigation, administrative agency proceedings, and other civil cases and advising non-profit organizations on public-interest litigation strategies. As part of his pro bono work, Charlie serves on the Junior Board of Chicago Volunteer Legal Services and co-directs the firm’s involvement in the Chicago Bar Foundation’s Investing in Justice Campaign.

Before joining the firm, Charlie served as a law clerk to the Hon. James B. Loken of the U.S. Court of Appeals for the Eighth Circuit. Before attending law school, Charlie worked as a paralegal in the Chicago office of an international market research company, where he focused on contract negotiation and drafting and intellectual property matters.
