About Cooper & Kirk

“In a town filled to the brim with lawyers, few firms in Washington, D.C., can lay claim to being as influential on a national stage as Cooper & Kirk.” (National Law Journal, 2022).

Cooper & Kirk is a litigation boutique that, as the National Law Journal recently wrote, “has been a player in many of the major events in American history over the last quarter-century.” Our firm has broad experience and extraordinary success in commercial, regulatory, and constitutional disputes in both federal and state courts. Since our founding over 25 years ago, we have been involved in many of the most significant trials and appeals in the country, usually against the nation’s largest and most sophisticated law firms. We relish this challenge and have won courtroom victories worth more than $10 billion for our clients. The key to our success is our people. As a boutique, we are able to limit our hiring to top graduates from the nation’s best law schools, who typically join our firm after federal appellate or Supreme Court clerkships. And thanks to our roughly one-to-one partner to associate ratio, our partners become intimately familiar with all aspects of our cases. Thus, our size has proven to be a source of strength because it enables us to serve our clients in an efficient and effective manner.
