Government Investigations & White Collar Defense


Enforcement actions against businesses and their principals have been a top priority for the U.S. Department of Justice, the SEC, and many other federal and state enforcement agencies and regulators. Actions by executives and employees that previously resulted in civil liability, now often serve as the basis for alleged corporate and individual criminal liability.

In this environment of heightened prosecutorial and regulatory scrutiny, our experienced Government Investigations and White Collar Defense team defends international, national, and local businesses as well as executives and other individuals accused of criminal, civil, or regulatory violations.


We partner with our clients' in-house counsel and key executives to ensure early, rapid, and effective response to criminal and regulatory investigations. Our attorneys are often called upon to conduct sensitive internal investigations involving alleged corporate wrongdoing. We also work collaboratively with Michael Best’s experienced, nationally recognized attorneys practicing within our corporate, intellectual property, healthcare, environmental, tax, securities, and labor and employment groups to resolve these matters.

Michael Best’s Government Investigations and White Collar Defense team is seasoned in all aspects of criminal and regulatory enforcement matters and often successfully resolves such matters without public charges, trial, or media scrutiny. We have represented corporate clients and individuals in all phases of the criminal process, from the initial government or grand jury investigation through trial, the appellate process, and any subsequent collateral enforcement actions. We routinely help clients respond efficiently to grand jury subpoenas and agency civil investigative demands, often doing so in a manner that avoids further agency action against our clients. We have successfully guided clients through parallel investigations by multiple agencies with separate enforcement agendas. We have also prepared witnesses to testify before Congress and other legislative or administrative hearings.

Our team is led by former prosecutors with extensive experience: a former Assistant U.S. Attorney for the District of Puerto Rico and state prosecutor, who has national experience handling complex criminal and regulatory matters; a former Assistant U.S. Attorney for the Northern District of Illinois, who has significant experience representing health care providers as well as government contractors; and a former Assistant U.S. Attorney for the Southern District of New York, who has experience with both federal intellectual property crimes and False Claims Act investigations. These seasoned former prosecutors are supported by others experienced in criminal defense and compliance issues.
