Professional experience

Partner in TozziniFreire’s White-Collar Crimes practice, Isadora has extensive experience in Criminal Law, representing the interests of Brazilian and multinational corporations in cases related to economic, financial, antitrust, tax, money laundering, frauds, biddings, bankruptcy-related issues, and environmental crimes. She has 19 years of experience in litigation, acting in State and Federal Courts, and before the Supreme Court. Her previous experience in well-known criminal law boutiques, combined to a full-service law firm, results in an efficient, technical, and multidisciplinary work. Her expertise also includes highly complex internal investigations involving more than one jurisdiction, C-level training, and implementation of programs aimed at combating corruption, preventing money laundering, and improving corporate governance. As an executive director at IDDD (Instituto de Defesa do Direito de Defesa), she participated in the conception, strategic planning, and management of projects to strengthen the Rule of Law, access to justice and criminal defense.


Isadora is recommended by Chambers Brazil and Análise Advocacia 500 and mentioned by GIR 100, which recognizes our White-Collar Crimes area as one of the world’s leading investigation practices. In 2021, she was recognized in the Women in Business Law guide, by Expert Guides.
