Partner, New York

Oliver J. Armas

Oliver Armas is the Managing Partner of our New York office. Ollie is sought out by our clients around the world to resolve some of their most complex and delicate matters – in domestic and foreign litigation, before arbitration tribunals, and to conduct sensitive internal investigations. In just the past year, Ollie represented a Korean client in a US$1 billion putative RICO class action, a Saudi agent against its Argentine principal in a US$100 million ICC arbitration, a Brazilian owner in three international construction arbitrations totaling almost US$1 billion in claims, a US healthcare provider in a AAA “mass arbitration” brought by multiple doctors, the government of Mongolia in defending enforcement of an UNCITRAL and Energy Charter Treaty arbitration award in DC (involving the U.S. Foreign Sovereign Immunities Act), and a US-based client in an FCPA investigation in Latin America.
Ollie leads a team that is multi-lingual and multi-cultural, and they pride themselves in creatively and tenaciously resolving their clients’ disputes involving energy (oil and gas, power, renewables), mining, engineering, manufacturing, construction, licensing, commodities, franchising, agency disputes, financial products and services, M&A (including purchase price adjustments and earn outs), shareholder issues, joint ventures, hospitality, electronics, technology, transportation, and pharmaceutical and life sciences.
Ollie has handled international arbitrations under the rules of the major arbitral institutions, including the ICC, AAA/ICDR, LCIA, ICSID, DIAC, and UNCITRAL. He is also a highly sought after arbitrator. Because Ollie is fluent in Spanish (and can understand Portuguese), he routinely counsels clients on matters involving Latin America. He has acted as a legal expert in certain aspects of U.S. law in Mexico and Peru, and has supervised litigation and conducted FCPA investigations in almost every country in Latin America.

Clients and peers say that Ollie is "incredibly smart and energetic" (Chambers Global); "very thoughtful and inventive; he created arguments others wouldn't have thought of" (Chambers USA); "wonderfully sharp" (Chambers Latin America); "highly analytical and provides key strategic advice" (The Legal 500).
