Ms. Sinderson is involved in a variety of the firm’s practice areas, including securities fraud, corporate governance, and advisory services. She is currently a member of the teams prosecuting securities class actions against Salix Pharmaceuticals, Dole, GNC and SunEdison, and litigation arising from the failure of the major mid-Atlantic bank, Wilmington Trust.  

Most recently, Ms. Sinderson played a key role in two of the firm’s largest cases in its history, both of which settled near trial for billions of dollars on behalf of investors.  In In re Merck Securities Litigation, she was a member of the small trial team which resulted in a $1.062 billion settlement.  If approved by the Court, this settlement would be the second largest recovery ever obtained in the Third Circuit, one of the top 10 recoveries of all time, and the largest recovery ever achieved against a pharmaceutical company. She was also a member of the trial team prosecuting In re Bank of America Securities Litigation, which resulted in a recovery of $2.425 billion, the single largest securities class action recovery ever resolving violations of Sections 14(a) and 10(b) of the Securities Exchange Act and one of the largest shareholder recoveries in history. 

Ms. Sinderson has also been part of the trial teams in several additional securities litigations through which the firm has successfully recovered hundreds of millions of dollars on behalf of injured investors. She was a member of the trial team that prosecuted the action against Washington Mutual, Inc. and certain of its former officers and directors for alleged fraudulent conduct in the thrift’s home lending operations, an action which resulted in a recovery of $208.5 million, one of the largest settlements achieved in a case related to the fallout of the subprime crisis and the largest recovery ever achieved in a securities class action in the Western District of Washington. She was also a part of the trial teams that prosecuted the In re Bristol-Myers Squibb Co. Securities Litigation, which resulted in a recovery of $125 million, as well as In re Biovail Corporation Securities Litigation, which resulted in a recovery of $138 million for defrauded investors and represents the second largest recovery in any securities case involving a Canadian issuer.

Ms. Sinderson was recently recognized as a national “Rising Star” by Law360 for her work in securities litigation.  She was also named to Benchmark Litigation’s “Under 40 Hot List,” which recognizes her as one the nation’s most accomplished legal partners under the age of 40.
