Mark and the Kirkland team out-lawyered, out-argued and out-shined the other attorneys, hands down. - Senior Counsel, Baxter Healthcare

Mark Premo-Hopkins is a trial partner in Kirkland’s Chicago office. He represents companies as both plaintiffs and defendants in a broad range of business disputes. Mark recently won a jury trial in Delaware state court, where the court entered judgment of more than $100 million for his client based on defendants’ fraud in the sale of a clinical trial software business. The American Lawyer selected Mark and his partner as Litigator of the Week based on the win.

Mark also served as lead trial counsel for a crop protection company vindicating its rights in an R&D joint venture worth hundreds of millions of dollars. As trial counsel for AbbVie, Mark won injunctive relief against a former employee that secretly joined a competitor. And Mark went to trial for Baxter Healthcare in its successful defense of a $400 million breach of contract suit, which eventually ended in a favorable settlement.

Mark has deep experience on behalf of private equity sponsors and their portfolio companies, while also serving as trial counsel in complex litigation matters for some of the world’s largest pharmaceutical and agrichemical companies. His clients benefit from the unique perspective and strategic insights he gained during four years as a successful plaintiff’s attorney.

When he’s not trying cases, Mark is an avid golfer and loves working with kids. He coaches youth sports for his local Park District.
