Ariel joined Clare Locke as an Associate in 2019. Her practice is dedicated to complex commercial litigation, defamation, and advising clients facing high-profile reputational attacks. Prior to joining Clare Locke, Ariel began her legal career at one of the nation’s premier law firms, Kirkland & Ellis LLP. While at Kirkland, Ariel was a key member of both the litigation and international trade & national security practice groups. She represented a broad range of clients–including individuals, Fortune 500 companies, private equity sponsors, and hedge funds–in diverse industries, including aerospace and defense, chemicals, energy, financial services, and real estate.

Ariel’s litigation practice focuses on complex trial litigation, appellate litigation, white collar criminal defense, and strategic counseling.  She has represented clients before federal and state courts across the country, including matters involving defamation, government investigations, antitrust proceedings, contract disputes, trade secrets, fraud, immigration law, and constitutional law. She has experience in all stages of litigation, from pre-litigation strategy and advice to trial preparation and execution.

As a member of Kirkland’s international trade & national security group, Ariel focused on national security reviews by the Committee on Foreign Investment in the United States (CFIUS), export controls (ITAR and EAR), trade and economic sanctions (OFAC), customs, anti-boycott restrictions, anti-money laundering (AML) regulations, and compliance with the U.S. Foreign Corrupt Practices Act (FCPA). She advised a range of clients on complex issues arising from mergers and acquisitions, cross-border transactions, and internal and government investigations. Ariel worked with clients to prepare license applications, disclosures, and other filings to U.S. regulatory agencies and to develop and implement risk-based compliance policies.

Ariel maintains an active pro bono practice and has received multiple pro bono service awards.  While at Kirkland, she was part of the appellate litigation team that represented death-row petitioner Ivan Teleguz in his actual-innocence hearings, federal habeas corpus appeals and other proceedings related to Teleguz’s capital sentence. On April 20, 2017, Virginia Gov. Terry McAuliffe granted a petition for clemency filed by Kirkland lawyers on behalf of Teleguz, marking the first clemency decision commuting a death sentence in Virginia since 2008.
