Overview

Dilworth Paxson LLP’s Plaintiff’s Rights practice dates back to the pioneer of the modern-day class action – Harold Kohn.  We have deep experience in all aspects of complex commercial, class and representative litigation from building successful litigation strategies to obtaining class certification, securing discovery, negotiating settlements, conducting trials, and handling all aspects of appeals.

Dilworth is one of the few firms to offer a 360-degree perspective as our [insert number] litigators and trial attorneys routinely represent both plaintiffs and defendants in complex litigation. This experience in devising and implementing litigation and trial strategies for plaintiffs and defendants benefits our clients on both sides of the “v.”
