Sailfish Law Illinois Trial Lawyer
Sailfish Law is the solo litigation practice of Peter D. McLaughlin, an Illinois trial attorney with more than a decade of experience representing businesses and executives in high-stakes commercial and employment litigation. Peter handles every matter personally and uses AI to assist with certain document-heavy projects that once required teams of associates. Where the case fits, he shares risk with his clients through contingency arrangements, flat fees, and fee caps.
Peter brings a broad foundation to his litigation practice. A former fixed-income trader on Wall Street, Peter clerked in federal court for two years before litigating complex commercial disputes at two of the world's leading litigation firms, Sidley Austin and Quinn Emanuel. He also worked in litigation finance at one of the industry's largest funders, underwriting commercial litigation investments and learning firsthand how lawsuits are valued and won. That perspective, formed on the trading floor, in the courtroom, and at the investment desk, sharpens how he reads a case and how he handles it.
