Justin S. Nematzadeh focuses his practice on securities fraud litigation. He was recently named a Rising Star under 40 years of age by Law360, a prestigious honor awarded to a select few “top litigators and dealmakers practicing at a level usually seen from veteran attorneys.” He was also honored by Super Lawyers® as a 2018 Rising Star.

Justin played a key role in the Firm’s securities class action case against Brazil’s largest oil company, Petrobras, arising from a multi-billion-dollar kickback and bribery scheme, in which the Firm, as sole Lead Counsel, recently achieved a historic $3 billion settlement for the Class, as well as precedent-setting legal rulings. 

Prior to joining Pomerantz in 2015, Justin practiced at Gibson, Dunn & Crutcher LLP. His practice at Gibson Dunn involved federal and state complex litigation and internal and regulatory investigations, focusing on securities and antitrust litigation. Additionally, for his work in representing plaintiffs in Toney-Dick v. Doar, he was awarded a 2013 Pro Bono Publico award from The Legal Aid Society.

Justin earned his J.D. degree, cum laude, from Fordham University School of Law. During law school, he served as a member of the Fordham Urban Law Journal and as a business editor of the Fordham Dispute Resolution Society. Additionally, he served as a judicial intern to the Honorable Stuart M. Bernstein of the United States Bankruptcy Court for the Southern District of New York. He earned his B.B.A. degree, with distinction, from the University of Michigan Stephen M. Ross School of Business, with an emphasis in finance and corporate strategy. During business school, he was awarded a University of Michigan Alumnae Council MBNA Scholarship.
