Ryan McCarl


Ryan McCarl has represented clients in high-stakes appellate and trial litigation in a variety of practice areas. He has drafted merits briefs, dispositive motions, and writ petitions in cases before state and federal courts including the United States Supreme Court. His expertise in legal writing and strategy helps clients develop innovative and successful arguments in complex disputes.

Ryan’s arguments and briefs have been decisive in several cases. A Tenth Circuit panel agreed with his preclusion argument and disposed of a decade-long antitrust suit against a global medical supplies manufacturer. The New York Court of Appeals cited a brief he drafted in establishing a right to a cautionary jury instruction in cross-race eyewitness identification cases. And the Illinois Supreme Court relied on a First Amendment overbreadth and due process argument he developed in unanimously striking down an Illinois statute prohibiting non-consensual audio recording.

Before joining GMSR, Ryan was an associate at two prominent litigation firms and a clerk for the Honorable David M. Ebel on the United States Court of Appeals for the Tenth Circuit. He has published articles and book chapters on diverse topics including substantive due process, constitutional vagueness doctrine, sovereign debt arbitration, and homeowners associations.

Additionally, Ryan has created a language-learning application called WordBrewery, which teaches high-frequency vocabulary using real sentences from newspapers around the world.
