Langer, Grogan & Diver P.C. is a Philadelphia-based law firm that focuses on complex litigation, particularly antitrust and consumer protection matters.

The firm was founded as boutique litigation firm that would divide its time between major commercial matters, particularly on behalf of small business, and law in the public interest, with its most recent emphasis in the area of consumer protection. Its antitrust work has received the American Antitrust Institute’s award for Outstanding Antitrust Litigation Achievement in Private Law Practice and its work in the public interest has been frequently recognized, most recently by the Philadelphia Bar Association’s, William V. Brennan Award for pro bono work.

The firm has obtained the largest consumer recovery within the Third Circuit and, prior to forming the firm in 2002, Howard Langer had been lead counsel in the case obtaining what was then the largest antitrust recovery within the circuit.

Among the firm’s awards for its work in the public interest are the Equal Justice Award of Community Legal Services of Philadelphia, the Pro Bono Award of the Hebrew Immigrant Aid Society, and the Social Justice Award of the Jewish Social Policy Network. In addition, the firm has established the Langer Grogan & Diver Social Justice Fellowship at the University of Pennsylvania Law School, which annually pays the first-year salary of a law graduate entering public interest law.

LGD’s lawyers have been at the forefront of many hallmark cases, including:

Linerboard Antitrust Litigation, 305 F.3d 145 (3d Cir. 2002)
