Criminal Defense and Governmental Investigations
Few events can be as damaging to an individual or a company as becoming the focus of criminal litigation or a governmental investigation. When your reputation, livelihood and business are at stake, you cannot afford to settle for anything less than the quality, experienced representation provided by Quarles & Brady LLP.

Our Criminal Defense and Governmental Investigations practice is made up of seasoned attorneys with significant trial experience. Our lawyers exclusively focus on the defense of individuals and companies in cases and matters across the country.

Our attorneys have a well-deserved reputation for their effective representation of clients in the full range of corporate compliance and white collar criminal matters, including comprehensive governmental investigations and grand jury investigations involving:

  • Accounting and Financial Services
  • Antitrust
  • Charitable Gifts
  • Customs
  • Government Contracting/ False Claims Act
  • Health Care Fraud and Abuse
  • Immigration/Employer Sanctions
  • Mail and Wire Crimes
  • Public Corruption
  • Real Estate Including Land Exchanges
  • RICO
  • Securities
In conjunction with our white collar criminal defense practice, we have a well-established practice representing individual defendants and victims in traditional criminal cases involving:
  • Assault/Aggravated Assault
  • Embezzlement/Theft
  • Fraud and Money Laundering
  • Immigration
  • Vehicular Crimes and DUI
  • Computer Crimes
  • Defense Against Juvenile Offenses
  • Post Conviction Relief/Appeals/Clemency
  • Alleged Sexual Misconduct
  • Substance Abuse
Responding to investigations or allegations of wrongdoing is essential to a successful defense effort. Recognizing the benefits of conducting investigations prior to the filing of formal charges, we routinely conduct pre-indictment investigations and vigorously work to prevent the filing of criminal charges.

We understand our clients’ need for cost-effective representation, and are committed to the philosophy that value is a function of experience, quality service and results.
