Clients rely on Matt for his innovative solutions to their business challenges from areas spanning antitrust and consumer protection investigations, state and federal False Claims Act litigation, to matters involving corruption of government officials.

As the leader of Husch Blackwell’s State Attorneys General Practice and a member of the firm’s White Collar, Internal Investigations & Compliance team, Matt represents and advises clients in a wide variety of lawsuits and regulatory disputes across the United States. In an era of heightened state-level regulatory scrutiny and enforcement, Matt’s practice involves regularly interfacing with state attorneys general and their staffs and assisting companies in navigating complicated legal, public relations and crisis management hurdles.

Matt’s practice focuses particularly on defending corporations and individuals accused of consumer fraud and violations of antitrust laws, healthcare fraud, and other violations of federal and state law. Matt has represented clients in high-profile matters before the U.S. Attorney for the Southern District of New York, the U.S. Department of Justice (DOJ) Antitrust Division and the Federal Trade Commission (FTC). Matt is experienced in helping clients respond to grand jury subpoenas and civil investigative demands.

Matt assists clients in protecting what is most important to them, and he achieved what is believed to be the first permanent injunction under the Defend Trade Secrets Act of 2016 (DTSA). Matt regularly prosecutes affirmative civil litigation in federal court to protect client intellectual property.
