Daniel L Geyser

Lawyer information

Practice Areas

Dan is widely recognized as one of the nation’s leading Supreme Court and appellate litigators. He has argued thirteen SCOTUS cases in private practice, more than any other active Texas or Colorado lawyer. He recently 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 NLJ’s “Appellate Hot List,” earned weekly honors as a Law360 “Legal Lion,” achieved national appellate rankings in multiple publications, and has been listed among the “veritable who’s who of the Supreme Court bar” (Empirical SCOTUS). In 2019, Law360 named Dan one of its “Appellate MVPs,” an honor awarded to only four lawyers in the United States.

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, patents, ERISA, arbitration, and bankruptcy). For plaintiffs, he has crafted legal strategy in matters generating over a half-billion in recovery. For defendants, he has won appeals in 8- and 9-figure disputes. He has special expertise at the rehearing stage, and handles landmark state-court appeals (arguing repeatedly before the Texas Supreme Court).
