Kessler Topaz Meltzer & Check, LLP

With offices in Radnor, Pennsylvania and San Francisco, Kessler Topaz Meltzer & Check, LLP is one of the largest and most successful plaintiff-side shareholder litigation firms. It acts on behalf of states attorneys’ general offices and public and private entities, among them municipalities, state agencies, mutual fund managers, sovereign wealth funds, and multi-employer welfare funds. The corporate governance and M&A department handles matters in state and federal courts across the country, as well as being highly active in Delaware. Lee Rudy, Daniel Albert and Eric Zagar, who are all based in the Radnor office, are the key partners. Rudy, who practices in the area of corporate governance litigation with a focus on transactional and derivative cases, and Albert, who has a strong track record in recovering substantial damages for breaches of fiduciary duties, are preparing for a trial arising from a class action related to Discovery, Inc.’s 2022 acquisition of AT&T. Newly promoted partner Grant Goodhart also plays a key role in that matter. Darren Check, who manages the firm’s portfolio monitoring and claims filing service, SecuritiesTracker, also stands out for his role in key matters.
