Diandra “Fu” Debrosse is a partner at DiCello Levitt LLP. She is a fearless plaintiffs’ attorney who fights unapologetically for individuals and public entities injured by wrongful conduct, whether by defective medical devices, drugs, or cosmetics, environmental contamination, corporate misconduct, or civil rights abuse. Nationally recognized as a powerhouse in mass torts, class actions, products liability, discrimination, and sexual assault claims, Fu has recovered nearly $1 billion in damages for her clients.

His reputation for innovatively taking on tough cases has led to his appointment to leadership positions in many historic and headline-grabbing litigations.

Adam served as co-lead counsel in three of the largest biotechnology class actions in U.S. history, helping recover more than $1.7 billion on behalf of plaintiffs and creating a game- changing economic model to measure crop contamination damages that set the modern industry standard.
