A formidable advocate in a complex class action defense

When our Wisconsin-based manufacturing company was named in a significant product liability class action, the stakes were immense. We needed counsel who was not only technically brilliant but also strategically calm under pressure. John Rocco of von Briesen & Roper was precisely that. His deep focus in mass tort and class action defense for defendants was immediately evident. He meticulously deconstructed the plaintiffs' arguments, guiding us through every deposition and motion with remarkable clarity. His background, including his recognition in commercial litigation and insurance law, proved invaluable as the case intertwined with our coverage issues. While his recent Lawyer of the Year accolade speaks volumes, it was his day-to-day dedication—returning calls promptly, explaining complex legal concepts in plain English, and his relentless preparation—that truly defined our experience. The matter was resolved favorably at summary judgment, a direct result of his early and aggressive case strategy. John is the rare attorney who combines Princeton and Marquette-honed intellect with a practical, client-centered approach. We cannot recommend him highly enough for any business facing complex litigation in Milwaukee.
