In Memoriam: Murielle Steven Walsh
It is with deep sadness that we announce the passing of our dear friend and partner, Murielle Steven Walsh, peacefully in her home on June 20, 2026, after succumbing to cancer.
In 1998, Murielle was hired as an associate at Pomerantz by then-Managing Partner, Stanley M. Grossman, who became one of her valued mentors.
Murielle rose through the ranks at Pomerantz to become a Senior Partner as well as the Firm’s Administrative Partner, earning her ascent through successful prosecution of corporate wrongdoing.
Murielle led the Firm’s groundbreaking securities class action against Wynn Resorts, alleging that Wynn management covered up a decades-long pattern of sexual misconduct by Steve Wynn while publicly denying that Wynn had engaged in any wrongdoing. In January 2025, the Court granted final approval to a $70 million settlement on behalf of defrauded investors. This is one of the largest— if not the largest—securities class actions tied solely to #MeToo-related allegations.
By litigating this case through to its highly successful resolution, Murielle and her team paved the way for addressing #MeToo allegations via securities litigation and demonstrated that corporate accountability in this area is indeed important to investors.
Murielle received many well-deserved awards for her legal work over the years. Most recently, she was named, for the second time, an Elite Woman of the Plaintiffs’ Bar by the National Law Journal. When Law360 crowned her a 2024 Titan of the Plaintiffs Bar, it published an article that is worth the read both for Murielle’s description of her path to the law and a description of her by an admiring colleague outside of Pomerantz.

According to the Firm’s current Managing Partner, Jeremy A. Lieberman, Murielle “played an instrumental role in the Firm’s success over the past three decades. Beyond her undisputed legal acumen, she was a wonderful friend to so many of us, whose good nature, cheerfulness and common sense formed an integral part of the Firm’s culture.”
A highly accomplished attorney, loving wife to Sean and devoted mother to Peyton, Murielle was a role model for other working women. Passionately supportive of her family and friends, she also found time to give to others. She served on the Board of Trustees of the non-profit organization Court Appointed Special Advocates for Children (“CASA”) of Monmouth County, New Jersey, which trains volunteers to watch over and advocate for children removed from their homes due to abuse or neglect, and helps them find suitable long-term care. CASA volunteers ensure that these children don’t get lost in the overburdened legal and social service system or languish in inappropriate group or foster homes.
Murielle is survived by her husband Sean, daughter Peyton Grace Walsh, father Alain Steven (Sélima), brother Didier (Lauren), nephews Jackson and Clay Steven, niece Frankie Steven, and brother-in-law and “second brother” Brian Walsh (James).
