Daniel Collins is a nationally recognized trial lawyer who represents clients in a variety of complex litigation matters. An award-winning former federal prosecutor, Dan regularly interacts with the Department of Justice, the Securities and Exchange Commission and other government agencies. Dan co-leads the firm’s litigation practice group, comprising over 250 lawyers and other professionals.

Dan is a fellow of the American College of Trial Lawyers, a distinction reserved for the top one percent of trial lawyers across the United States and Canada. He also has been recognized repeatedly by Chambers USA: America’s Leading Lawyers for Business, in which clients and peers have described him as “a very savvy, tactical and hard-working lawyer who is held in high esteem in the community” with “first rate cross-examination skills” and “a great bed-side manner.”

During his 10-year career as an assistant United States attorney for the Northern District of Illinois, Dan led a number of significant prosecutions and trials, including the international investigation of those responsible for the planning of the November 2008 terrorist attacks in Mumbai, India, a case featured in Frontline PBS’s “A Perfect Terrorist.” Dan held several supervisory positions, including deputy chief of the financial crimes and special prosecution section and acting chief of the general crimes section.

Internal Investigations

Dan has led numerous internal investigations on behalf of Fortune 100 corporations as well as smaller privately held organizations on a wide spectrum of issues, including securities and accounting fraud, health care fraud, the Foreign Corrupt Practices Act (FCPA), pay-to-play regulations, antitrust, money laundering, and trade secret theft. Dan has advised clients on self-disclosure issues and on navigating issues presented by DOJ’s Principles of Federal Prosecution of Business Organizations.

White Collar Defense

Dan has defended companies and individuals with the primary goal of persuading authorities not to bring charges. When necessary, however, Dan has aggressively defended clients’ interests and obtained favorable results at trial. For example, in a recent high-profile, health care fraud trial, Dan obtained the dismissal of all felony charges for his client after six weeks of trial. According to the Chicago Tribune, the case “fizzled in stunning fashion in the midst of trial.”

Dan has lectured extensively in the United States and abroad on a variety of enforcement issues facing companies, including international sanctions and export controls, FCPA and internal controls relating to fraud. As a prosecutor, Dan was a faculty member at the Department of Justice’s National Advocacy Center, where he spoke about complex issues in FISA/CIPA litigation. Dan also has taught courses in trial advocacy, national security, and computer crime at law schools in Chicago.
