ABOUT US
Strategic Counsel for a Connected Hemisphere

Based in Washington, D.C., we combine deep regional insight with decades of experience across the United States, Latin America, and the Caribbean. We advise global businesses, international organizations, and sovereign clients on strategic legal matters, regulatory strategy, and cross-border transactions.
Our work sits at the intersection of law, public policy, technology, and investment—leveraging innovations such as artificial intelligence to deliver forward-looking solutions that bridge jurisdictions and unlock opportunities across borders.
MISSION
Our mission is to turn legal complexity into strategic clarity—across borders, sectors, and systems of power.
SERVICES
WHERE LAW AND POLICY ALIGN WITH STRATEGY
We connect capital, institutions, and public power through sound legal strategy and regional fluency. From cross-border transactions to regulatory compliance, we provide the legal direction that drives results across the Americas.
PRACTICE AREAS
Transactions, Investment and Compliance
From market entry to complex regulation, we help clients anticipate challenges, seize opportunities, and manage corruption risks across the Americas.
We negotiate agreements that protect our clients’ interests while enabling efficient execution, and we guide them in preventing, detecting, and addressing corruption risks across jurisdictions.
The result: investments and transactions that move forward with confidence, integrity, and strategic advantage.
Navigating Law, Policy & Power
We help clients navigate the intersection of law, policy, and power. With deep insight into U.S., Latin American, and Caribbean political landscapes, we provide forward-looking counsel on regulatory change, legislative momentum, and strategic stakeholder engagement.
From advancing business goals to anticipating policy shifts or protecting hard-earned reputations, we craft agile public affairs strategies that align legal goals with government realities—locally, regionally, and globally
Strategic Dispute Resolution
We represent clients in complex disputes that cross borders, industries, and jurisdictions.
Our team leverages trusted tools—international arbitration, mediation, and cross-border litigation—to resolve disputes efficiently and strategically.
Where litigation is unavoidable, we coordinate proceedings across jurisdictions with precision and global perspective, ensuring that our clients’ interests are protected at every stage.
