Glenn Chappell is chair of Tycko & Zavareei LLP’s Appellate Practice Group. He and his team primarily represent consumers, plaintiffs, and public interest groups in high-impact appellate litigation. He briefs and argues cases in appellate courts across the country, most recently including the United States Supreme Court (one principal brief and three amicus curiae briefs in the past year), numerous federal circuit courts (more than a dozen appeals in the past year), and state appellate courts. He has significant experience at every stage of pursuing and defending appeals, including oral argument, principal and amicus curiae brief writing, petitions for certiorari and interlocutory review, and motions practice.

Mr. Chappell believes the best appellate lawyers have intimate first-hand knowledge of how a case is tried. Accordingly, he also maintains an active litigation practice in the trial courts. He is currently serving as Discovery Chair in two multidistrict litigation proceedings and class counsel representing millions of consumers at both the trial and settlement stages in multiple cases. He also routinely serves as embedded appellate counsel in trial court proceedings, advising co-counsel on crucial issues in the case with an eye toward future appellate proceedings. He and his colleagues have secured victories for their clients at every level from trial courts to courts of last resort.

Before joining Tycko & Zavareei, Mr. Chappell was an associate in the Washington, D.C. office of Gibson, Dunn & Crutcher LLP. During his time at Gibson Dunn, he practiced in the firm’s award-winning Appellate and Constitutional Law and Litigation practice groups. He also maintained an active pro bono practice that focused on police and sentencing reform.

Mr. Chappell graduated summa cum laude from Duke University School of Law in 2017. After graduation, he clerked for the Honorable Gerald Bard Tjoflat of the United States Court of Appeals for the Eleventh Circuit and the Honorable Anthony J. Trenga of the United States District Court for the Eastern District of Virginia. His articles and scholarly publications have appeared in multiple publications, including Law360, the Duke Law Journal, and the University of Richmond Law Review.

Tycko & Zavareei LLP’s Appellate Practice Group represents consumers, whistleblowers, and the public interest in state appeals courts, the federal circuit courts of appeals, and the United States Supreme Court. We handle appeals in the firm’s own cases and also handle or assist with appeals on behalf of other law firms in the class action and qui tam spaces.

We bring fresh and creative perspectives to cases on appeal and present clear, focused, and powerful arguments in our written and oral advocacy. We pride ourselves on the thoroughness of our research and our mastery of the law and record in each case. We also deeply appreciate the importance of keeping sight of the big picture. Accordingly, we strive in each appeal to tell a consistent narrative of the case that is both persuasive and enjoyable to read.

Members of our Appellate Practice Group possess impeccable credentials. Our team members graduated from Duke, Harvard, Columbia, Berkeley, and University of Chicago law schools. We draw on the experience gained in three federal appellate clerkships, three federal district court clerkships, and one clerkship for a judge on the District of Columbia’s highest court.
