Murielle Steven Walsh graduated cum laude from New York Law School in 1996, where she was the recipient of the Irving Mariash Scholarship. During law school, Murielle interned with the Kings County District Attorney and worked within the mergers and acquisitions group of Sullivan & Cromwell. Murielle was recognized as a 2018 Lawyer of Distinction, an honor bestowed upon less than 10% of attorneys in any given state. 

Murielle joined the Firm in 1998 and became a partner in 2007. During her career at Pomerantz, Murielle has prosecuted highly successful securities class action and corporate governance cases. She was one of the lead attorneys in prosecuting In re Livent Noteholders’ Securities Litigation, a securities class action in which she obtained a $36 million judgment against the company’s top officers, a ruling which was upheld by the Second Circuit on appeal. Murielle was also part of the team litigating the EBC I v. Goldman Sachs case, where the Firm obtained a landmark ruling from the New York Court of Appeals, that underwriters may owe fiduciary duties to their issuer clients in the context of a firm-commitment underwriting of an initial public offering.

Murielle, along with Senior Partner Jeremy Lieberman, manages the Firm’s case against Corinthian Colleges, one of the largest for-profit college systems in the country, for alleged misrepresentations about its job placement rates, compliance with applicable regulations, and enrollment statistics. Pomerantz prevailed in the motion to dismiss proceedings, a particularly noteworthy victory because Chief Judge George King of the Central District of California had dismissed two prior lawsuits against Corinthian with similar allegations. She is currently litigating Ruiz v. Citibank, No. 10-cv-5950 (S.D.N.Y); Thorpe v. Walter Investment Management Corp., No. 14-cv-20880 (S.D. Fla.); and Klein v. Conformis, No. 15-CV-13295 (D. Mass.).

Murielle serves on the Board of Trustees of the non-profit organization Court Appointed Special Advocates for Children (“CASA”) of Monmouth County. She also serves on the Honorary Steering Committee of Equal Rights Advocates (“ERA”), which focuses on and discusses specific issues that women face in the legal profession. ERA is an organization that protects and expands economic and educational access and opportunities for women and girls. In the past, Murielle served as a member of the editorial board for Class Action Reports, a Solicitor for the Legal Aid Associates Campaign, and has been involved in political asylum work with the Association of the Bar of the City of New York.

Murielle is admitted to practice in New York, the United States District Court for the Southern District of New York, the United States Court of Appeals for the Second Circuit and the United States Court of Appeals for the Sixth Circuit.

Murielle serves on the Firm's Anti-Harassment and Discrimination Committee.
