John J. Grogan, a founding partner of the firm, specializes in complex litigation in the areas of constitutional law and civil rights, consumer law and antitrust law. John Grogan and Howard Langer founded the firm in 2004. Since that time, John has focused his practice on antitrust, consumer rights and constitutional matters. Most recently, John has focused on litigation using RICO to bring mainstream financial institutions to account for their participation and facilitation of fraudulent schemes victimizing consumers. John, along with other members of the firm, secured a jury verdict against a California based loan servicer. The case, Aliff et. al. v. Vervent, Inc., 20-0697 (S.D. Cal. 2023) is among the very few cases successfully tried to verdict using RICO’s conspiracy provision.

In the antitrust area, John has represented clients in large matters involving the intersection of antitrust law and intellectual property especially in the pharmaceutical context. John served with others in the firm as antitrust counsel for a large generic pharmaceutical manufacturer in a series of high-profile antitrust matters. John is also an active litigator in public interest matters focusing on Constitutional law and civil rights particularly as those areas intersect with problems afflicting the poor, immigrants and persons with AIDS.
