Justine represents individuals and companies in high-stakes criminal matters and complex regulatory proceedings. Praised by Chambers USA as “very strong…amazing…a fighter,” she draws on two decades of courtroom experience – including nine years as a federal public defender – to defend and protect her clients when their liberty and livelihoods are at stake.

Justine is known for her rigorous advocacy and unwavering dedication to her clients’ needs. She routinely obtains jury acquittals, wins pretrial motions to dismiss, and achieves favorable sentencing outcomes; many of her clients have had their charges reduced or were able to avoid criminal or civil liability altogether. Her criminal defense 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 also represents individuals in sensitive federal and state grand jury proceedings; internal investigations; and investigations conducted by government agencies, including the SEC, the Consumer Financial Protection Board, and the New York State Attorney General.

Prior to joining Sher Tremonte, Justine was a partner and co-founder at the litigation boutique Colson & Harris LLP. From 2001 to 2010, she served as an assistant federal defender for the Eastern District of New York, where she was lead counsel on hundreds of criminal cases in federal court. Her experience also includes an associate position at Kramer Levin Naftalis & Frankel LLP; in this role, she worked on a wide variety of criminal and civil cases, including civil enforcement actions before the SEC and the NASD, commercial arbitrations, and various pro bono and commercial civil matters.
