Pryor Cashman announced today that Katherine C. Reilly has been named co-chair of the firm’s White Collar + Regulatory Enforcement Practice, effective immediately.

Since joining Pryor Cashman in early 2025 after more than a decade as a federal prosecutor in the U.S. Attorney’s Office for the Southern District of New York, Kate has built a practice advising corporations, financial institutions, and individuals on high-stakes government investigations, internal compliance matters, and litigation strategy. She represents clients in matters brought by the Department of Justice, the SEC, the CFTC, OFAC, and state regulators, as well as on internal investigations and compliance strategy.

During her time in government, Kate served as chief of the Southern District’s Complex Frauds & Cybercrime Unit. As a prosecutor, Kate tried or supervised more than a dozen criminal jury trials. She supervised the prosecution of groundbreaking actions including the first criminal charges for music streaming fraud facilitated by AI-generated content, a first-of-its-kind prosecution arising from a hack of the Ethereum blockchain, and the first ever conviction stemming from a hack of a decentralized financial exchange.

In private practice, Kate has been recognized by Chambers USA in Litigation: White-Collar Crime & Government Investigations (New York), and been named a New York City Elite Lawyer in White Collar by Legal 500 and one of Lawdragon’s 500 Leading Litigators in America.

Kate will lead the practice alongside existing chair Sidhardha “Sid” Kamaraju. Pryor Cashman’s White Collar + Regulatory Enforcement Practice handles the full spectrum of sophisticated white collar and regulatory matters, from defending individuals charged with significant criminal offenses, to representing corporations embroiled in complicated government investigations, to conducting internal investigations for companies facing crisis. The practice has experienced significant growth in the recent years and now includes four former federal prosecutors. In addition to welcoming Kate, since 2024, the practice has added partners David Abramowicz, former in-house counsel at GE Vernova and Deputy Chief of Appeals at the U.S. Attorney’s Office for the Southern District of New York, and Jasmine Juteau, who joined after a long career at a prominent criminal defense boutique.

“Kate arrived with a record in government that speaks for itself, and at Pryor Cashman she has earned the immediate trust of clients and colleagues alike,” said David C. Rose, managing partner of Pryor Cashman. “White collar work has long been a strength of the firm, and it remains one of the areas where we are investing most seriously. Kate and Sid together give the practice leadership that will propel its next stage of growth.”

“Kate is an exceptional attorney, leader, and colleague. Since arriving at Pryor Cashman, Kate has demonstrated the skill, judgment, and creative thinking necessary to guide our clients through some of their most complicated and challenging moments,” said Sid, who worked with Kate as a prosecutor in the Southern District of New York. “As Kate steps into her new role, I am confident that she will continue to advance the tremendous growth of our group, and I’m honored to share that role with her.”

“I feel so fortunate to have joined Pryor Cashman and to have this opportunity to help to build the White Collar + Regulatory Enforcement Practice, alongside Sid, my friend and former SDNY colleague,” said Kate. “Our group is dedicated to bringing Pryor Cashman’s tradition of personal care and attention to the most complex and significant white-collar matters. To help to lead this incredible collection of lawyers at a time of such significant growth for the practice is truly a privilege.”
