Experience

Sherman Marek, the principal attorney of Marek Law Office, has investigated and litigated complex commercial matters in state and federal courts for over 25 years, particularly antitrust violations and fraud on the federal government. Currently, Mr. Marek represents whistleblowers in several pending False Claims Act qui tam lawsuits and investigations. Among other roles, he was previously lead counsel in a whistleblower action on behalf of the City of Chicago and State of Illinois against several Wall Street banks in connection with their home mortgage lending activities. Mr. Marek was also lead counsel in a whistleblower action on behalf of the federal government against a nationwide healthcare supply company, which settled in 2011 for $85 million—one of the largest recoveries in history where the government did not actively litigate a qui tam action on its own behalf. He was also lead counsel for the plaintiff class in a multi-billion dollar antitrust class action against dozens of healthcare systems and medical associations seeking fair wages and safe work hours for medical residents. That case, which compelled the defendants to immediately adopt weekly work hour limits for residents, was followed widely in the national media, led Mr. Marek to meet with several members of Congress, and was litigated up to the United States Supreme Court.

Mr. Marek’s broad experience is reflected by the many court decisions published in his cases, including: City of Chicago and State of Illinois ex rel. Martinez v. Citigroup, Deutsche Bank, Goldman Sachs, JPMorgan Chase, Merrill Lynch and Morgan Stanley, No. 12-C-1814 (N.D. Ill. Sep. 17, 2012); U.S. ex rel. Mason v. Medline, 731 F. Supp. 2d 730 (N.D.
