Cassandra Webster Lenning joined Heller, Huron as an Associate Attorney in 2015.

Prior to joining the firm, Ms. Lenning worked at a small non-profit organization and associated law firm, which partner to litigate complex international human rights cases under the Alien Tort Statute and Torture Victim Protection Act. She represented plaintiffs in state and federal courts across the country, seeking to hold multinational corporations accountable for human rights abuses. Through her prior law firm, Ms. Lenning also litigated civil rights, employment, and plaintiff-side tort cases, as well as appellate matters. Her employment practice included litigating cases under Title VII of the Civil Rights Act of 1964 and the Fair Labor Standards Act (FLSA).

Before that, Ms. Lenning was at the Washington Lawyers’ Committee for Civil Rights and Urban Affairs, where she worked with both the Equal Employment Opportunity Project and the Immigrant and Refugee Rights Project. She assisted in representing immigrant plaintiffs in civil actions for violations of state and federal employment statutes, including the Family and Medical Leave Act (FMLA), the FLSA, and state wage and hour laws. Many of her cases also involved civil rights claims under Title VII, particularly for sexual harassment, pregnancy discrimination, or discrimination based on race and/or national origin. Ms. Lenning got her start as a Policy Advocacy and Legal Fellow with the American Civil Liberties Union of Washington State.

Ms. Lenning graduated from Duke University School of Law, and received her undergraduate degree from the University of Washington in Seattle. She is admitted to practice in the District of Columbia and the Commonwealth of Virginia, as well as several federal courts.
