Frederick R. Yarger


P. 303.244.1990 | F. 303.244.1879
"Exceptionally gifted . . . one of the brightest legal minds I've ever encountered."
—Former Colorado Attorney General Cynthia Coffman


Fred Yarger, the former Solicitor General of Colorado, represents clients in high-stakes appeals and complex litigation nationwide. He has been on the front lines of dozens of precedent-setting cases in a wide range of legal areas. In the U.S. Supreme Court, Fred has litigated more than 20 cases as counsel of record and argued four separate times—including in a case described by national media as a “blockbuster” and a case listed among the “top five” most significant of a recent court term. In trial courts, Fred develops sophisticated strategies that protect his clients’ interests and seek to favorably shape the law.

In every case, whether at trial or on appeal, Fred partners with his clients to find creative ways to advance their business priorities. In addition to his trial and appellate successes, Fred’s government experience helps him advocate for clients before state and federal regulatory and investigative agencies. 

Fred’s written advocacy has been recognized by top appellate and Supreme Court litigators; he is a three-time winner of the National Association of Attorneys General “Best U.S. Supreme Court Brief” award. In 2018, Law Week Colorado named Fred a Top Litigator, and the Denver Business Journal recognized him in its annual “Who’s Who in Energy” for his successes litigating issues affecting the oil and gas industry. Before joining WTO, Fred was a partner in an AmLaw 20 firm.
