April Denise Seabrook serves as Special Counsel in the Appellate Practice of Duane Morris’ Trial Practice Group. Her practice focuses on appellate litigation and strategic motion practice at the trial level. She partners with trial teams nationwide to shape legal strategy at every stage of litigation—identifying dispositive issues, developing persuasive legal theories, preserving arguments, and building records designed to support early resolution and withstand appellate scrutiny.
Ms. Seabrook brings nearly two decades of litigation, regulatory, and investigative experience spanning government enforcement, complex civil litigation, white-collar defense, and internal investigations. Drawing on experience from both sides of the adversarial table, she delivers strategic, forward-looking advocacy that anticipates opposing arguments and distills complex factual and legal issues into clear, compelling briefs in state and federal courts across the country.
Ms. Seabrook’s broad strategy-driven perspective is rooted in more than seven years as an Assistant United States Attorney (AUSA) in the Civil Division of the U.S. Attorney’s Office for the District of Columbia, where she defended the federal government and its agencies in more than 300 cases. Her work covered a wide range of matters, including:
- Administrative Procedure Act challenges
- Freedom of Information Act litigation
- Federal employment discrimination cases under Title VII, the ADEA, and the Rehabilitation Act
- Constitutional claims, tort actions, and immigration-related litigation
She also served in the Office’s Criminal Appellate Division, briefing criminal appeals before the D.C. Court of Appeals and the D.C. Circuit.
Before joining the U.S. Attorney’s Office, Ms. Seabrook spent seven years in private practice. She represented individuals and corporate clients in complex civil litigation and white-collar matters, including multidistrict pharmaceutical litigation, and defended against state and federal government investigations and enforcement actions under False Claims Acts, anti-kickback statutes, and consumer protection laws.
Immediately before joining Duane Morris, Ms. Seabrook spent three years as Senior Litigation Counsel in the Enforcement Division of the Consumer Financial Protection Bureau (CFPB), where she investigated and prosecuted enforcement actions against financial service providers. She advised agency leadership on litigation risk and strategy and built cases under statutes including:
- Consumer Financial Protection Act
- Truth in Lending Act
- Fair Credit Reporting Act
- Fair Debt Collection Practices Act
- Real Estate Settlement Procedures Act (RESPA)
She co-led the Bureau’s first litigated enforcement action under the SAFE Act.
Her career across multiple practices and perspectives gives her a grounded understanding of how cases are built, briefed, and won in the trial court and on appeal.
