    Reiss brings nearly 25 years of experience handling antitrust class actions and is known for representing both plaintiffs and defendants. Per a statement, he will focus on leading direct-action affirmative recovery litigation on behalf of corporate clients who allege harm from competitors, suppliers, or strategic partners.

    At Crowell, Reiss will also work within the firm’s Recovery Practice, collaborating with attorneys across disciplines to help corporate and institutional clients pursue recoveries that extend beyond traditional class action settlements, according to a statement. The firm said his experience in managing intricate cases and guiding clients through multifaceted litigation will play a key role in strengthening its recovery capabilities.

    Reiss joins Crowell from Robins Kaplan, where he served as a partner and led the firm’s New York antitrust group. Over the course of his career, he has secured more than $1.2 billion in recoveries for clients in complex antitrust class actions, per a statement.

    Among his notable matters, Reiss previously acted as co-lead counsel representing direct purchasers of Keurig K-Cups in antitrust litigation against Keurig. According to a statement, he is expected to continue similar work at Crowell on behalf of direct-action clients. In addition to his litigation practice, he has advised clients across industries on a range of antitrust compliance and competition issues.

    Daniel A. Sasse, chair of Crowell’s Antitrust & Competition Group, praised the addition in a statement: “Will is a tenacious litigator known for his creative approach to problem solving, meticulous case management, and success in building collaborative teams that work seamlessly with clients and co-counsel. He understands how to deliver litigation results that prioritize our clients’ business goals from the start.”

    Reiss also commented on his move, stating, “Crowell’s Antitrust and Competition Group is a market leader, and their highly sophisticated Recovery Practice is trusted by the most prominent companies in the world. I am excited to join this growing team, which works in close partnership with its clients to recover damages and achieve their business goals in an increasingly complex environment.”

    The firm noted that Reiss’s arrival follows several other additions to its antitrust team in recent years, including Kenneth Dintzer, formerly a deputy branch director in the National Courts Section of the U.S. Department of Justice’s Civil Division, and trial partner Eric P. Enson, according to a statement.

    Beyond his law firm work, Reiss serves as chair of the New York State Bar Association’s Antitrust Law Section and holds a Band 2 ranking in Chambers USA for plaintiff antitrust litigation. He has also been recognized in The Legal 500 and was named an “Antitrust and M&A Trailblazer” by The National Law Journal in 2018, per a statement.

    In addition, Reiss sits on the Board of Directors of the Young Center for Immigrant Children’s Rights. His pro bono efforts have included representing families affected by the September 11 attacks in hearings before Special Master Kenneth Feinberg in connection with the September 11th Victim Compensation Fund, according to a statement.
