Who is Devin Weinberg from Jeopardy? Meet the Commercial Litigation Attorney and Federal Law Clerk from Denver

Devin Weinberg is an American commercial litigation attorney based in Denver, Colorado, where he practices as an Associate Attorney with León Cosgrove Jiménez, LLP, a boutique law firm focused on complex business disputes and commercial litigation. Through a career that has included federal judicial clerkships, appellate work, private practice, and legal research, Weinberg has established himself as an emerging attorney in Colorado’s legal community.

In 2026, Weinberg gained national attention after appearing as a contestant on Jeopardy!. His appearance came during an already successful period in his legal career, having recently returned to private practice following two prestigious federal judicial clerkships and receiving recognition in Best Lawyers: Ones to Watch® in America for his work in commercial litigation.

Practicing Commercial Litigation in Denver

Devin Weinberg is an Associate Attorney at León Cosgrove Jiménez, LLP, a boutique litigation firm with offices in Denver and Miami that specializes in complex commercial disputes and business litigation.

He first joined the firm’s Denver office in September 2022, before leaving temporarily in April 2023 to accept a federal judicial clerkship. Following the completion of that clerkship, he returned to the firm in October 2024, where he continues to represent clients in sophisticated commercial litigation matters.

Commercial litigation involves resolving disputes between businesses and organizations through negotiation, arbitration, and court proceedings. Cases often involve contract disputes, partnership disagreements, business torts, fiduciary duties, corporate governance, and other high-value commercial matters requiring extensive legal research and courtroom advocacy.

Working at a boutique litigation firm allows Weinberg to focus on complex legal disputes while handling matters that frequently require detailed factual analysis, strategic planning, and appellate-level legal writing.

Serving in Prestigious Federal Judicial Clerkships

Before returning to private practice, Weinberg completed two highly competitive federal judicial clerkships that provided valuable experience working alongside members of the federal judiciary.

From May 2023 through September 2024, he served as a Judicial Law Clerk for the United States District Court for the District of Colorado. District courts serve as the primary federal trial courts, where judges oversee civil and criminal proceedings, evaluate evidence, rule on legal motions, and conduct jury and bench trials.

Before that appointment, Weinberg clerked for the United States Court of Appeals for the Tenth Circuit from August 2021 through August 2022. Federal appellate courts review legal questions arising from district court decisions and play an important role in shaping legal precedent across multiple states.

Judicial clerkships are among the most respected early-career positions within the legal profession. Clerks assist judges by researching legal issues, drafting judicial opinions, reviewing briefs, and analyzing complex questions of law before cases are decided.

Serving at both the trial and appellate levels gave Weinberg firsthand experience with the federal judicial process from multiple perspectives.

Building Experience Across the Legal Profession

Even before beginning his federal clerkships, Weinberg had accumulated experience across a wide range of legal settings.

While attending law school, he worked as a Summer Associate at Perkins Coie LLP, one of the United States’ largest international law firms. Summer associate programs provide law students with practical experience working alongside practicing attorneys while introducing them to complex commercial legal work.

He also served as a Legal Volunteer with the City of Chicago Department of Law’s Appeals Division, where he gained experience in appellate practice and government litigation.

Additional legal experience included a Legal Internship with Lawyers for the Creative Arts, supporting artists and creative professionals with legal matters, and a position as a Research Assistant at the University of Miami School of Law, assisting with academic legal research.

Earlier still, he completed a Judicial Internship with the United States District Court for the Southern District of Florida, working with two federal judges and gaining an early introduction to judicial decision-making.

Together, these roles provided experience across private practice, public service, nonprofit legal work, academic research, and the federal court system.

Academic Excellence Across Multiple Universities

Weinberg’s legal career has been built upon an impressive academic foundation spanning several universities.

He earned his Juris Doctor with Honors from the University of Chicago Law School in 2021, after transferring from the University of Miami School of Law, where he completed his first year of legal studies during the 2018–2019 academic year.

While at the University of Chicago, he served as a member of the prestigious University of Chicago Law Review, one of the nation’s leading student-edited legal journals. Membership on a law review is typically reserved for students who demonstrate exceptional academic performance and legal writing ability.

Outside the classroom, Weinberg also participated in the Law School Musical, balancing rigorous legal studies with extracurricular involvement.

Before attending law school, he completed a Master of Arts in International Relations at the University of Florida in 2018, where he participated in Model United Nations and Florida Players, reflecting interests in diplomacy, public speaking, and theatre.

He previously graduated summa cum laude from Florida Atlantic University in 2016, completing his bachelor’s degree with the highest academic distinction.

Professional Recognition and Legal Admissions

As his career has progressed, Weinberg has earned recognition for his work in commercial litigation.

Beginning in 2026, he was included in Best Lawyers: Ones to Watch® in America for Commercial Litigation. The publication recognizes lawyers who are early in their careers but have already demonstrated professional excellence within their respective practice areas.

In addition to his professional recognition, Weinberg is admitted to practice law in both Colorado and Illinois.

He is also admitted before the United States District Court for the District of Colorado and the United States Court of Appeals for the Tenth Circuit, allowing him to represent clients in both federal trial and appellate courts.

These admissions reflect his experience across multiple levels of the American legal system and his growing reputation within the commercial litigation field.

Interests Beyond the Courtroom

Outside his legal career, Weinberg has maintained interests in the performing arts and community service.

From October 2015 through April 2016, he volunteered as a House Manager and Usher with Theatre Lab, supporting theatre productions and helping audiences during performances. The experience reflected an interest in arts and cultural programming that complemented his later legal work.

His participation in Florida Players during graduate school and the University of Chicago Law School Musical also demonstrated a longstanding appreciation for theatre and performance.

These experiences illustrate a well-rounded background that combines rigorous legal scholarship with involvement in creative and community-based activities.

From the Courtroom to the Jeopardy! Stage

Devin Weinberg’s appearance on Jeopardy! in 2026 showcased the breadth of knowledge developed through years of academic achievement, legal scholarship, and professional practice. As a commercial litigation attorney with León Cosgrove Jiménez, LLP, he has built a career handling complex business disputes while drawing upon experience gained through prestigious federal judicial clerkships at both the trial and appellate levels.

His professional journey has included work in private practice, government law, nonprofit legal services, judicial chambers, and legal academia, supported by degrees from Florida Atlantic University, the University of Florida, the University of Miami School of Law, and the University of Chicago Law School. Recognition in Best Lawyers: Ones to Watch® in America further reflects his growing reputation within the legal profession.
