Catalina Vergara

O'Melveny & Myers LLP

Catalina Joos Vergara, a partner in the firm’s Financial Services practice group, specializes in crafting perceptive and responsive solutions to complex disputes. She believes that an effective litigator must first be a mindful listener—that clients are best served by individualized, cost-efficient strategies, not a one-size-fits-all playbook.

Catalina is also a skilled trial lawyer and appellate advocate who recognizes that a successful representation calls for a comprehensive trial and appellate strategy, even at the earliest stages of a case. Her guidance has helped financial services, insurance, pharmaceutical, and consumer goods companies navigate high-stakes nationwide litigation.

ERISA matters are a significant part of Catalina’s portfolio.  She represents retirement plan sponsors and service providers in class actions brought by plan participants alleging the plan’s fiduciaries breached their fiduciary duties or committed “prohibited transactions” in selecting and monitoring plan investment options, or in causing the plan to pay excessive fees.

At present, Catalina is representing a number of major financial, energy, and entertainment companies in ERISA fiduciary breach cases pertaining to the companies’ 401(k) plans.  Outside of the ERISA context, Catalina represents financial institutions in a range of complex civil matters, including claims brought by borrowers against mortgage servicers and claims brought by account holders challenging bank overdraft fees.

A native Spanish speaker and a member of the Pacific Council on International Policy, Catalina also brings a global perspective to her practice. She has counseled clients facing litigation and government investigations abroad, including in Latin America.

She has also devoted significant time to representing Spanish-speaking immigrants pro bono, both before the Ninth Circuit and in the immigration courts.

Catalina was O’Melveny’s 2012 Leadership Council on Legal Diversity Fellow, and she speaks regularly on diversity in the legal profession. Within O’Melveny, she serves on the Women’s Advisory Board and the Diversity Council, and co-founded both the Women Attorneys’ Network and the Community Involvement Committee in her office.

For her contributions, Catalina was awarded a Warren Christopher Values Award, an honor bestowed on those who exemplify the Firm’s legacy of excellence, leadership, and citizenship.
