Anna C. Haac

Anna C. Haac is a Partner in Tycko & Zavareei’s Washington, D.C. office. She focuses her practice on consumer protection class actions and whistleblower litigation. Her prior experience at Covington & Burling LLP, one of the nation’s most prestigious defense-side law firms, gives her a unique advantage when representing plaintiffs against large companies in complex cases. During her time at Covington, Ms. Haac represented corporate clients in high stakes cases, focusing her practice on complex civil litigation, white collar defense work, and employment disputes. Among other matters, Ms. Haac represented Fortune 500 companies in government investigations into violations of federal laws and regulations, advised employers on applicable federal and state employment laws, and litigated on behalf of companies and individuals in patent, insurance, and other civil matters.

Since arriving at Tycko & Zavareei, Ms. Haac has represented consumers in a wide range of practice areas, including product liability, false labeling, deceptive and unfair trade practices, and predatory financial practices. She also serves as the D.C. Co-Chair of the National Association of Consumer Advocates. Her whistleblower practice involves claims for fraud on federal and state governments across an equally broad spectrum of industries, including health care fraud, customs fraud, and government contracting fraud. During her tenure at Tycko & Zavareei, Ms. Haac has helped secure multimillion dollar relief on behalf of the classes and whistleblowers she represents. In addition, she has been instrumental in securing key appellate victories, including a recent landmark decision by the U.S. Court of Appeals for the Third Circuit, which held as a matter of first impression that the evasion of customs duties for failing to mark imported goods with their foreign country of origin gives rise to a claim under the False Claims Act.

Ms. Haac earned her law degree cum laude from the University of Michigan Law School in 2006 and went on to clerk for the Honorable Catherine C. Blake of the United States District Court for the District of Maryland. Prior to law school, Ms. Haac graduated with a B.A. in political science with highest distinction from the Honors Program at the University of North Carolina at Chapel Hill.

Ms. Haac is a member of the District of Columbia and Maryland state bars. She is also admitted to the United States Court of Appeals for the Second, Third, and Fourth Circuits and the United States District Courts for the District of Columbia, District of Maryland, and the Eastern District of Michigan.
