Greenberg Traurig Adds Environmental and Product Liability Litigator Matthew J. Douglas to Denver Office
"Matthew J. Douglas joins Greenberg Traurig as a shareholder in Denver to strengthen its environmental, toxic tort and product liability practice."
Douglas brings a nationally recognized practice focused on environmental, toxic tort, and product liability litigation, with particular depth in the energy, manufacturing, and pharmaceutical industries. He joins Greenberg Traurig from Arnold & Porter, where he spent 27 years developing a robust complex litigation practice.
Douglas’s broad trial experience informs his work. His environmental practice covers the lifecycle of contaminated site and accidental release disputes, including initial response and investigations, enforcement actions, contribution claims, class action defense, CERCLA litigation and remediation, toxic tort claims, PFAS water contamination cases, Natural Resource Damages claims, and Clean Water Act enforcement matters. On the product liability side, he has served as trial and national counsel in large-scale pharmaceutical mass tort litigation and has defeated class certification in consumer fraud matters.
Over his career Douglas has tried dozens of cases as first-chair trial counsel across Colorado and numerous other jurisdictions. His matters have included high-profile litigation such as the Deepwater Horizon Gulf of Mexico oil spill, where he served as counsel to BP on natural resource damages matters and its internal investigation. He also has represented household-name companies in complex PFAS class action and personal injury litigation, and has acted as national counsel for major pharmaceutical companies in multidistrict litigation and defended nationwide mass tort litigation involving multiple trials.
