Daniel Sadeh is a founding partner of Halper Sadeh LLP. Mr. Sadeh received his Bachelor of Arts in 2012 from Queens College of the City University of New York and received his Juris Doctor in 2015 from the Georgetown University Law Center. While attending Georgetown, Mr. Sadeh worked for the Attorney General for the District of Columbia.

Upon graduating from Georgetown, Mr. Sadeh became an associate at a national law firm representing investors in securities class actions and shareholder derivative lawsuits. There, he was actively involved in the litigation of numerous securities class actions resulting in substantial recoveries for investors, including, among others:

  • In re Galena Biopharma, Inc., Securities Litigation, No. 3:14-cv-00367 (D. Or.) ($20 million recovery);
  • Thomas v. Magnachip Semiconductor Corp., et al, No. 3:14-cv-01160 (N.D. Cal.) ($23.5 million recovery);
  • Beck v. Walter Investment Management Corp., et al, No. 1:14-cv-20880 (S.D. Fla.) ($24 million recovery); and
  • In re Montage Technology Group Ltd., Securities Litigation, No. 14-cv-00722 (N.D. Cal.) ($7.25 million recovery).

Mr. Sadeh has also obtained victories on behalf of his clients through precedential judicial opinions on novel areas of law. In Dartell v. Tibet Pharmaceuticals, Inc. et al, No. 2:14-cv-03620 (D. N.J. Jun 06, 2014), Mr. Sadeh was part of the team that successfully opposed the non-director, Board Observers’ summary judgment motions and obtained a precedential ruling that, despite their lack of voting power, these defendants may be held liable as “persons performing similar functions” to directors.

Prior to founding Halper Sadeh LLP, Mr. Sadeh also served as an associate at Bernstein Liebhard LLP. There, he represented pension funds, institutional investors, and individual investors in securities litigation, and identified and investigated potential violations of the federal securities laws.

Mr. Sadeh is admitted to practice in the State of New York and the United States District Courts for the Southern and Eastern Districts of New York.
