Where Advocacy Meets Business

“To help my clients achieve the best possible result in their disputes, I always strive to not only understand the complex technical or legal issues but also the commercial realities that underlie every matter.”

Gretta’s experience spans a broad range of commercial and investment disputes in domestic and international arbitration and in state and federal courts. She has worked on matters arising under the ICDR, AAA Employment, AAA Commercial, AAA Construction, BCICAC, ICC, LCIA, SCC, SMA, and UNCITRAL Rules. Her cases have included disputes concerning construction/infrastructure projects, energy projects such as oil & gas, wind, solar, coal-fired, and hydroelectric projects, licensing and distribution agreements, investment agreements, banking and finance, securities laws, manufacturing and sales contracts, employee disputes, executive compensation agreements, and healthcare management agreements.

Gretta is an adjunct professor at New York University Law School, where she teaches a course on international arbitration and the CISG and also co-coaches the Foreign Direct Investment and Vis International Commercial Arbitration moot court teams. She is also on the Executive Board for ICDR Y&I, the Steering Committee for CPR Y-ADR, and a member of the Arbitration Committee of the New York City Bar.


Prior to joining Chaffetz Lindsey, Gretta was an Associate at Mayer Brown, Legal Counsel at the Arbitration Institute of the Stockholm Chamber of Commerce, and a Visiting Lecturer at Stockholm University.
