Patrick V. Dahlstrom serves as Co-Managing Partner of Pomerantz. Mr. Dahlstrom joined Pomerantz in the fall of 1991 and became a partner in January 1996. In 2012, Benchmark Litigation named Mr. Dahlstrom a “Local Litigation Star” in Chicago.

Mr. Dahlstrom is a 1987 graduate of the Washington College of Law at American University in Washington,D.C., where he was a Dean’s Fellow, Editor in Chief of the Administrative Law Journal, a member of the Moot Court Board representing Washington College of Law in the New York County Bar Association’s Antitrust Moot Court Competition, and a member of the Vietnam Veterans of America Legal Services/Public Interest Law Clinic. Upon graduating, Mr. Dahlstrom served as the Pro Se Staff Attorney for the United States District Court for the Eastern District of New York and was a law clerk to the Honorable Joan M. Azrack, United States Magistrate Judge.

Mr. Dahlstrom is a member of the Firm’s Institutional Investor Practice and New Case Groups. He is the partner-in-charge in many of the Firms’ securities fraud class actions on behalf of institutional lead plaintiffs, including Comverse and In re Sealed Air Securities Litig., No. 03-cv-437 (D.N.J.). Examples of other notable litigations by Mr. Dahlstrom include In re Safety-Kleen Stockholders Securities Litigation (as co-lead counsel, the Firm obtained $54.5 million settlement) and In re Woolworth Corporation Securities Class Action Litigation (Pomerantz, as co-lead counsel, secured a $20 million settlement); and Groupon Securities Litigation (Pomerantz, as co-lead counsel, secured a $45 million settlement).

Mr. Dahlstrom’s extensive experience in litigation under the PSLRA has made him an expert not only at making compelling arguments on behalf of Pomerantz’s clients for lead plaintiff status, but also in discerning weaknesses of competing candidates. In re American Italian Pasta Co. Sec. Litig. and Comverse are the most recent examples of his success in getting clients appointed sole lead plaintiff despite competing motions by numerous impressive institutional clients. After appointing Pomerantz as sole lead counsel in American Italian Pasta, the court stated:

Pomerantz has significant experience (and has been extremely effective) litigating securities class actions, employs several highly qualified attorneys, and possesses ample resources to effectively manage the class litigation and protect the class’s interests.

Mr. Dahlstrom was also a member of the trial team in In re ICN/Viratek Sec. Litig. (S.D.N.Y.), which, after trial, settled for $14.5 million. Judge Wood praised the trial team:

[P]laintiffs counsel did a superb job here on behalf of the class . . . This was a very hard fought case. You had very able, superb opponents, and they put you to your task . . . The trial work was beautifully done and I believe very efficiently done.

In approving the $225 million settlement in In re Comverse Technology Inc. Sec. Litig., No. 06-CV-1825 (E.D.N.Y.) in June 2010, Judge Nicholas G. Garaufis stated:

The court also notes that, throughout this litigation, it has been impressed by Lead Counsel’s acumen and diligence. The briefing has been thorough, clear, and convincing, and . . . Lead Counsel has not taken short cuts or relaxed its efforts at any stage of the litigation.
