A senior partner at Seeger Weiss, Dave Buchanan represents individual and corporate plaintiffs in state and federal courts throughout the country. His practice focuses on litigating and trying complex commercial and product liability matters. Buchanan’s docket involves a wide variety of cases, including pharmaceutical injury, product liability claims, trade secrets, commercial disputes, pension challenges, securities and investment fraud, and consumer claims. Though the scope of his cases is broad, they are usually large, national, high-stakes cases, generally destined for trial. By their nature, they are often centered in federal multi-district proceedings or analogous state coordinated proceedings, where Buchanan is often selected by his co-counsel or appointed by the courts to lead them as liaison counsel, lead counsel, or a member of plaintiffs’ executive/steering committee.
