Giselle J. Joffre

Co-Chair, White Collar Crime & Government Investigations Practice

Corporations and executives call on me for strategic advice to resolve complex federal government investigations.

Giselle Joffre is Co-Chair of Foley Hoag’s White Collar Crime & Government Investigations Practice. A former federal prosecutor at the U.S. Attorney’s Office in Boston, she focuses her practice on defending corporations and executives in criminal and civil government investigations, including grand jury matters. She also leads targeted internal investigations of sensitive, high-profile matters.

She is experienced in the process of seeking a resolution of a government investigation, including the negotiation of settlement and compliance agreements. When investigations result in litigation, clients benefit from Giselle’s extensive civil and criminal litigation and jury trial experience. Giselle, known for her keen interpersonal skills and business acumen, has led sensitive internal corporate investigations concerning allegations of racial discrimination, physical and sexual harassment/abuse, mismanagement, corruption, and export control violations. Upon conclusion, she provides strategic advice concerning appropriate corporate actions.

While Giselle has practiced in a wide variety of industries, her expertise is in the life sciences and health care sectors, with representative clients including biotechnology, pharmaceutical, medical device, and diagnostic testing companies, hospitals, and universities. Recently, she has advised and defended diagnostic testing companies in federal litigation with respect to potential False Claims Act and Anti-Kickback Statute liability arising from marketing and billing practices. She brings an understanding of the prosecutorial perspective to the defense of her clients having prosecuted civil healthcare fraud matters, as well as various types of criminal fraud.

Giselle currently serves as counsel in the government-mandated compliance monitorship of a complex, global financial institution. In this role, she advises the monitor with respect to compliance risk assessment and investigates the implementation of the monitor’s recommended compliance improvements.

Prior to serving as a federal prosecutor, Giselle practiced at a Boston-based, national law firm. She earned her J.D. at Yale Law School and her A.B. in Economics, magna cum laude at Harvard College.
