A leading trial lawyer and white collar defense attorney, Justine represents companies and individuals in high-stakes trials, investigations, and litigations. Praised by Chambers USA as a “phenomenal advocate” and the “real deal,” Justine draws on two decades of courtroom experience – including nine years as a federal public defender – to advocate for and protect her clients when their liberty and livelihoods are at stake.

Known for her unwavering dedication to her clients and rigorous advocacy, Justine obtains jury acquittals in tough cases, wins pretrial motions to dismiss, and routinely achieves favorable sentencing outcomes. Many of her clients have had their charges reduced or were able to avoid criminal or civil liability altogether. Justine’s experience includes a wide range of complex financial and legal issues, including insider trading, securities fraud, bank fraud, campaign finance fraud, RICO, mortgage fraud, terrorism, obstruction of justice, bribery, and tax fraud. She has also represented executives, directors and officers, as well as companies and nonprofit entities, in sensitive and complex federal and state grand jury proceedings, internal investigations, and investigations conducted by government agencies including the SEC, the New York Attorney General’s Office, the CFTC, and the CFPB.

Justine has been honored as a fellow of the American College of Trial Lawyers, an exclusive association consisting of top trial lawyers from the United States and Canada. This invitation-only fellowship recognizes experienced trial lawyers who have demonstrated exceptional advocacy skills, ethical conduct, professionalism, and collegiality. She has frequently lectured on trial skills and federal criminal defense. She is ranked by Chambers USA in Band 2, White-Collar Crime & Government Investigations, and has consistently been recognized by Super Lawyers, Lawdragon, and Best Lawyers – USA. She serves on several boards and is currently vice-president of the NYCDL, and a board member of the Center for Appellate Litigation and the Federal Defenders of New York. She previously served as Chair of the Board of Directors for the Federal Defenders of New York. In 2022, she received the Gideon’s Promise Ian Yankwitt Equalizer Award in recognition for her leadership and work in seeking compassionate release for incarcerated individuals during the pandemic.
