Valarie Hays leads the Chicago office's White Collar Defense & Investigations practice. Valarie is a trial lawyer and former federal prosecutor who represents companies and individuals in government inquiries and complex commercial litigation in federal and state courts. She also conducts corporate internal investigations and advises clients on the execution of their compliance programs across a broad range of industry sectors, including healthcare, financial services, consumer products, and oil and gas. A first chair trial lawyer, Valarie has tried 17 jury trials over the course of her career and has obtained numerous multimillion dollar settlements for her corporate clients, typically after prevailing on summary judgment rulings.

Valarie is known for her strong courtroom presence, her strategic ability to find and leverage the weaknesses in her opponents' cases, and her success in winning challenging cases and obtaining prosecution declinations. Most recently, in 2022, she has obtained four prosecution declinations on behalf of her corporate and individual clients in Department of Justice ("DOJ") investigations involving alleged criminal antitrust violations, environmental violations, and False Claims Act ("FCA") violations. In 2021, following a three-week trial, she won an acquittal on all counts for her client, an attorney who was charged in a federal indictment with novel bankruptcy fraud theories. Valarie also represented a former Michigan State University professor who was charged with fraud in a three-week jury trial that resulted in a hung jury (with nine jurors siding with the defense). The government dismissed the indictment with prejudice shortly after the trial ended.

Valarie's clients also hire her to conduct sensitive investigations. Valarie recently was retained by a United States sports organization to conduct a workplace culture investigation. Valarie also was retained by the Board of Commissioners for the Chicago Park District to lead an independent investigation into the Chicago Park District's response to allegations of sexual assault and a widespread culture of sexual harassment, bullying, and hazing within the lifeguard community. Valarie also has been retained to conduct sensitive investigations related to the sexual assault of a hospital employee, the death of a student athlete, gender and racial discrimination, whistleblower retaliation, and police department practices.
