Wilkinson Stekloff Partners Cali Arat and Sarah Neuman were joined by Counsel Roxana Guidero on Lawdragon’s 2025 edition of 500 X – The Next Generation. This guide honors influential, up-and-coming attorneys across the legal spectrum who have been practicing for fewer than fifteen years, offering an exciting glimpse into the future of the profession.
Cali has appeared among Lawdragon’s 500 X every year since its inaugural guide in 2023. She is an experienced trial litigator, having played key roles on more than half of the firm’s trial teams, including serving in standup roles for high-stakes victories on behalf of Bayer subsidiary Monsanto in their Roundup litigation. Cali also played an integral part in resolving the NCAA’s name, image, and likeness litigation through its groundbreaking settlement, which received final approval from a district court judge in June. For these and other accomplishments, Chambers and Partners recently recognized her as “Up and Coming” in Nationwide Product Liability & Mass Torts and Legal 500 recommends her for Sports. She will next serve as trial counsel for Medtronic in the first bellwether trial in their hernia mesh products liability litigation.
Since joining the firm Sarah has been synonymous with success, having been a member of over a half-dozen winning trial teams. She played a crucial part in the firm’s trial win in the FTC’s suit challenging Microsoft’s $68.7 billion acquisition of Activision Blizzard, which was recently affirmed unanimously on appeal by the ninth circuit. Sarah now serves as a lead member of the team defending Cargill, the largest privately held company in America, in a series of civil antitrust cases alleging a conspiracy with the country’s other largest beef producers to constrain output and raise profits. Her antitrust prowess has been recognized by Chambers, naming her as “Up and Coming” among Washinton, D.C. Antitrust Litigation Specialists, and by Legal 500 in their Antitrust Civil Litigation category. Sarah was also named a D.C. Rising Star in 2024 by the National Law Journal and now makes her first appearance in a Lawdragon guide.
Roxy is also being recognized by Lawdragon for the first time, after rejoining the firm as Counsel in 2024. Roxy was an integral part of the trial team that won a massive victory for the NFL in their Sunday Ticket litigation, securing judgment as a matter of law. She has since taken on representation of industry giants Exxon, in their sprawling climate change litigation, Visa, defending against the DOJ’s antitrust complaint aimed at Visa’s debit card practices, and most recently Hewlett Packard Enterprise (HPE). Roxy was set to play a lead role defending HPE’s $14 billion acquisition of Juniper Networks, when on the eve of trial the DOJ dropped its challenge, agreeing to a resolution that maintains HPE’s vision of the deal. In addition to her litigation docket, Roxy teaches courses on Contracts and Antitrust at the USC Gould School of Law.
This deserved inclusion by Lawdragon exemplifies Wilkinson Stekloff’s founding mission—to develop the next generation of elite trial lawyers—with Cali, Sarah, and Roxy’s recognition a clear reflection of its success.
