Irene Ribeiro

Irene Ribeiro focuses her practice on commercial litigation, commercial arbitration (international and domestic), and international investment arbitration.  She represents companies, states and individuals in state and federal courts in the United States, as well as in administered and ad hoc domestic and international arbitrations under the rules of various arbitral organizations, including ICC, ICSID, ICDR, AAA, AAA CONSTRUCTION, ARIAS, BCICAC, SMA and UNCITRAL.

Irene specializes in complex, high stakes litigation in the United States and before arbitral tribunals, regularly engaging with lawyers from different jurisdictions to ensure a client’s litigation strategy in the United States is coordinated with its interests abroad. She also advises on how New York and U.S. federal law and procedure can be used to assist in foreign proceedings.

In the last 7 years, besides her regular commercial litigation and arbitration practice, Irene has devoted substantial time handling complex insurance and reinsurance coverage advice and litigation.  Over the years Irene has handled hundreds of matters for clients in a wide range of industries, including insurance, energy (oil and gas, ethanol, nuclear), telecom, technology, construction, mining, transportation, and maritime (demurrage, charter parties, international sales).

Irene has experience in civil and common-law legal systems.  Prior to joining Dunning Rievman & MacDonald LLP, Irene spent almost two decades in the disputes departments of some of the largest American and English law firms.  Irene has an extensive network in the United States, Latin America, Southern Europe and Brazil where she was born, obtained her first law degree and started her practice.

Irene is fluent in English, Portuguese, Spanish and French, and has also studied Greek.
