Ms. Sinderson is involved in a variety of the firm’s practice areas, including securities fraud, corporate governance, and advisory services.  She is currently leading the teams prosecuting securities class actions against FleetCor Technologies, Frontier Communications, and Novo Nordisk, as well as litigation arising from the failure of SunEdison, Inc. 

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 that achieved a $1.062 billion settlement.  This settlement is 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.  Most recently, Ms. Sinderson was a senior member of the team that led the securities litigation concerning Wilmington Trust, which resulted in a $210 million recovery for the class (pending court approval).

Ms. Sinderson has also been part of the trial teams in numerous other securities litigations that have successfully recovered hundreds of millions of dollars on behalf of injured investors.  She served as a senior member of the teams that recovered $210 million in In re Salix Pharmaceuticals, Ltd. Securities Litigation, and $74 million in the take-private merger litigation San Antonio Fire and Police Pension Fund et al v. Dole Food Co. et al.  She was also 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.  The action resulted in a recovery of $208.5 million, the largest recovery ever achieved in a securities class action in the Western District of Washington.  Some of her other prominent prosecutions include the In re Bristol-Myers Squibb Co. Securities Litigation, which resulted in a recovery of $125 million; and 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.

In 2016, Ms. Sinderson was recognized as a national “Rising Star” by Law360 for her work in securities litigation and was 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. She is also regularly selected as a New York “Rising Star” by Super Lawyers.
