Career
Daniel L. Geyser is Chair of the firm’s U.S. Supreme Court Practice and a member of its Appellate Group. He focuses on complex and high-stakes appellate litigation, representing clients in the Supreme Court of the United States and in courts of appeals nationwide. In the past three Terms alone, Dan has had five cert. petitions granted, argued six SCOTUS merits cases, and secured multiple wins in high-stakes disputes. He is a two-time Law360 “Appellate MVP” (an honor awarded to only four lawyers in the United States), and was recently named one of 12 lawyers who are “the future of the Supreme Court bar” (Law360, 2024).
Dan is among a select group of elite lawyers who regularly handle significant disputes in the U.S. Supreme Court. Listed among the “veritable who’s who of the Supreme Court bar” (Empirical SCOTUS, 2018), Dan has argued seventeen Supreme Court cases in private practice, including two arguments last Term. He has twice had three cert. petitions granted in a 12-month period (a feat matched by few global firms), and personally handled over 5% of the Court’s merits docket in OT 2018. He has been named to the National Law Journal’s “Appellate Hot List” (2018, 2022), earned weekly honors as a Law360 “Legal Lion” (2018, 2024), achieved national appellate rankings in Chambers USA and The Legal 500 (2019-2024), and was named OT 2017’s “top performing” brief-writer among the Court’s repeat players (based on a 2018 empirical study using brief-analyzing software). His petitions are regularly featured among the “Petitions of the Week” on SCOTUSblog, and he is a three-time winner of NAAG’s Best Brief Award for excellence in brief-writing before the Court (2008-2009, 2011). In the past half-decade, Dan ranks among the top five lawyers nationwide for total Supreme Court arguments in private practice, notching “rare victor[ies]” (SCOTUSblog, 2021) and “huge win[s]” (Reuters, 2019) in cases that industry experts said could not be won.
Beyond the Supreme Court, Dan handles high-stakes matters in appellate courts nationwide, litigating cases in virtually every major area of federal law (especially securities, bankruptcy, patents, ERISA, and arbitration). In addition to an active federal practice, Dan has handled landmark state-court appeals, including arguing seven times before the Texas Supreme Court.
