Expert Antitrust Counsel for a Complex Merger Review

Mark Rosman provided exceptional guidance during a challenging DOJ merger review. His deep expertise in antitrust litigation, honed over 13 years, was immediately evident. He translated complex legal theories into clear, actionable strategy for our board. His recognition by Best Lawyers in Antitrust Law was well-deserved, as his counsel was instrumental in securing a favorable outcome without litigation. Mark’s professionalism and calm demeanor under pressure were invaluable. I would confidently recommend him to any company navigating high-stakes antitrust matters in Washington, D.C.
