Mr Gregory Castaldo > Kessler Topaz Meltzer & Check, LLP > Radnor, United States > Lawyer Profile

Based in in Radnor, Pennsylvania, and San Francisco, California, Kessler Topaz Meltzer & Check, LLP is highly regarded as one of the leading players in securities litigation, its 27-partner practice having amassed a strong track record in representing states attorneys’ general offices, as well as public and private entities, including municipalities, state agencies, mutual fund managers, sovereign wealth funds, and multi-employer welfare funds. In the Radnor office, the practice is led by seven respected partners, with David Kessler and Darren Check the most active in this area of law. Together, they negotiated a $450m settlement for Sjunde AP-Fonden in the long-running litigation concerning misrepresentations made about the carrying value of Kraft Heinz assets, the sustainability of its margins, and the success of the company’s cost-cutting strategy in the wake of its 2015 merger. Sharan Nirmul and Richard Russo, Jr. are the lead partners in a new securities fraud class action concerning representations and omissions made by former executives of Signature Bank and its auditor KPMG about the bank’s emergent risk profile and deficient management of those risks that ultimately caused it to collapse in March 2023. Jennifer Joost and Gregory Castaldo also played key roles in that case. Matthew Mustokoff and Andrew Zivitz, who are involved in the high-profile case In re Celgene Corp. Securities Litigation, and key partner Naumon Amjed also play prominent roles in the practice.
