Who is Devin Weinberg from Jeopardy?

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 specializing in complex business disputes and commercial litigation. His career has combined private practice with prestigious federal judicial clerkships, giving him experience at both the trial and appellate levels of the U.S. legal system.

When Weinberg appeared as a contestant on Jeopardy! in 2026, he represented a profession built on analytical thinking, legal research, and persuasive advocacy. By that point, he had already established himself within Colorado’s legal community through work in commercial litigation, judicial service, and appellate law, while also earning national recognition as one of Best Lawyers: Ones to Watch® in America for Commercial Litigation.

Practicing Commercial Litigation at León Cosgrove Jiménez

Devin Weinberg serves as an Associate Attorney with León Cosgrove Jiménez, LLP, where he focuses on complex business and commercial litigation. The firm’s Denver office, located at 999 18th Street, Suite 1200S, represents businesses and individuals in sophisticated commercial disputes requiring strategic litigation and courtroom advocacy.

Weinberg initially joined the firm in September 2022 before departing in April 2023 to accept a federal judicial clerkship. After completing that appointment, he returned to the firm’s Denver office in October 2024, continuing his practice in commercial litigation.

Commercial litigation encompasses disputes involving contracts, business relationships, fiduciary duties, corporate governance, fraud claims, partnership disagreements, and other complex legal issues between businesses and organizations. Attorneys practicing in this area must combine extensive legal research with strategic case management and courtroom advocacy.

Working within a boutique litigation firm has allowed Weinberg to concentrate on sophisticated commercial disputes while building expertise in one of the legal profession’s most demanding practice areas.

Serving the Federal Judiciary

One of the defining features of Weinberg’s legal career has been his service as a federal judicial law clerk.

From May 2023 through September 2024, he served as a Judicial Law Clerk for the United States District Court for the District of Colorado, assisting a federal judge with legal research, drafting judicial opinions, reviewing motions, and analyzing complex legal questions arising in civil and criminal litigation.

Before joining the District Court, Weinberg clerked for the United States Court of Appeals for the Tenth Circuit from August 2021 through August 2022. Federal appellate courts review legal decisions made by district courts and issue opinions that shape legal precedent across multiple states.

Judicial clerkships are widely regarded as among the most prestigious early-career positions available to attorneys. Clerks work directly with judges, providing research and legal analysis while gaining a detailed understanding of judicial decision-making and courtroom procedure.

Having served at both the trial and appellate levels, Weinberg developed experience with every stage of federal litigation, from initial proceedings through appellate review.

Developing Experience Across Multiple Legal Settings

Before entering federal judicial service, Weinberg built an impressive foundation through internships, clerkships, and legal positions across both the public and private sectors.

During law school, he worked as a Summer Associate at Perkins Coie LLP, gaining practical experience at one of the country’s largest international law firms. Summer associate programs provide law students with exposure to sophisticated legal matters while working alongside experienced attorneys.

He also served as a Legal Volunteer with the City of Chicago Department of Law’s Appeals Division, where he assisted with appellate litigation involving municipal legal matters.

His additional legal experience included a Legal Internship with Lawyers for the Creative Arts, an organization providing legal services to artists and creative professionals, and a position as a Research Assistant at the University of Miami School of Law, where he supported legal scholarship and academic research.

Earlier still, Weinberg completed a Judicial Internship with the United States District Court for the Southern District of Florida, working for two federal judges and gaining valuable courtroom experience before beginning his legal career.

These varied experiences exposed him to litigation, appellate practice, judicial decision-making, legal research, nonprofit legal services, and complex commercial law.

Academic Excellence from Florida to Chicago

Weinberg’s legal career is supported by a strong academic background that spans several respected 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 attending the University of Chicago, he served as a member of the University of Chicago Law Review, one of the nation’s leading student-edited legal journals. Membership on a law review is generally reserved for students who demonstrate exceptional academic performance and legal writing ability.

Outside academics, he participated in the Law School Musical, reflecting interests beyond the classroom. During his time at the University of Miami, he was active in both the Cardozo Legal Society and Books and Buddies, participating in student organizations alongside his legal studies.

Before law school, Weinberg completed a Master of Arts in International Relations at the University of Florida in 2018, where he participated in Florida Players and Model United Nations, developing interests in international affairs, public speaking, and performance.

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

Professional Recognition and Bar Admissions

As Weinberg’s legal career has progressed, he has earned recognition for his work within the legal profession.

Beginning in 2026, he has been recognized in Best Lawyers: Ones to Watch® in America for Commercial Litigation. The publication honors attorneys who have demonstrated outstanding professional achievement during the early stages of their legal careers.

Weinberg is admitted to practice law in both Colorado and Illinois, allowing him to represent clients in state courts in both jurisdictions.

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, reflecting his experience in both federal trial and appellate litigation.

These admissions and professional honors underscore his growing reputation as a commercial litigator and appellate practitioner.

A Longstanding Interest in Theatre and Community Service

Although law has become his profession, Weinberg has also maintained an interest in the performing arts and community involvement.

Between October 2015 and April 2016, he volunteered as a House Manager and Usher for Theatre Lab, helping support theatre productions and audience services. The volunteer role reflected an appreciation for arts and cultural programming outside his academic and professional pursuits.

His interest in theatre continued during graduate school through participation in Florida Players, and later at the University of Chicago Law School, where he performed in the Law School Musical.

These extracurricular activities demonstrate a balance between rigorous legal training and creative pursuits, illustrating interests that extend beyond the courtroom.
