Sassi Riar is a member of the Government Investigations & White Collar Practice and focuses on white collar criminal defense, regulatory enforcement and internal investigations. She helps clients facing allegations of white collar criminal, civil and regulatory violations avoid prosecution and minimize potentially damaging outcomes. Having been based in the Middle East for six years prior to returning to Washington DC, Sassi has particular expertise handling cases involving economic sanctions, anti-money laundering and counter terrorism financing (AML-CTF) laws and regulations, export controls, bribery and corruption, and bank fraud. She assists clients with crisis management and counsels senior management for entities across the Middle East and Africa, Levant, Europe and South Asia through multi-agency, multijurisdictional financial crime investigations and enforcement actions. She conducts high-level compliance assessments, based on industry standards, legal requirements and international best practices, to identify deficiencies or conduct issues that could give rise to enforcement liability. Sassi works closely with senior-level executives to develop comprehensive and customized solutions to resolve gaps, improve processes, reform compliance functions and internal controls, and assuage risks to business operations.

In 2021, Sassi was selected by a multinational telecommunications services provider, currently operating in 16 countries across Asia, the Middle East and Africa, for an extended secondment, due to her in-depth knowledge of sanctions and money laundering laws. During her secondment, Sassi provided sanctions compliance and anti-money laundering advisory counsel, drafted a group-level global sanctions and export controls policy, presented a sanctions and export controls training for more than 100 globally situated employees, and conducted a risk assessment of each of its subsidiaries.
