Keller and Heckman’s Environmental and Toxic Tort Litigation attorneys take an integrated approach to defending and counseling its clients, pairing their litigation and regulatory expertise with the firm’s in-house scientific staff, thus allowing the firm to efficiently craft and implement defense strategies while always considering the client’s business needs.

We defend clients in all types of litigation matters, including federal and state class and mass tort actions, as well as single plaintiff cases, in arbitration and mediation proceedings, and as national trial coordination counsel. The practice group also routinely represents clients in enforcement actions before administrative and industry-sanctioned bodies.

Whatever the forum, Keller and Heckman litigators and regulatory defense lawyers are well- positioned to bolster each client’s legal arguments and present the strongest scientific and technical case possible. We have defended numerous products in a wide range of industries, such as chemical, pesticide, oil and gas, paint and coating, paper and wood, food, electronics, packaging, and pharmaceutical. Prior matters have involved issues ranging from soil and drinking water contamination, airborne deposition and transport of heavy metals, and exposures to allegedly hazardous materials in consumer products.

Our attorneys have scientific and technical backgrounds that allows them to work effectively with clients. Many have served in the same industries as the firm’s clientele, including global chemical and engineering companies, environmental consulting serving the utility, mining, and oil/gas sectors, and manufacturing trade associations. They have degrees in areas such as chemical engineering and environmental science and policy. The practice group also counts among its members a former trial attorney at the United States Department of Justice, Environmental Torts Section.

Keller and Heckman is a leader in bringing an interdisciplinary approach to problem solving with over 25 in-house scientists, most of whom have Ph.Ds. or other graduate level degrees. Our scientists have expertise in a broad range of relevant areas, such as chemistry, toxicology, and risk assessment, and have collectively worked for decades in advising companies in the manufacturing and consumer product sectors. 

Keller and Heckman’s vast scientific knowledge base, coupled with our attorneys’ litigation experience, allows the firm to effectively defend its clients at the intersection of science and law.
