Representative Matters

Toxic Tort Exposure

Anthony has regularly litigated toxic tort exposure cases involving constituents such as metalworking fluids, formaldehyde, woodworking constituents, asbestos, benzene and sulfur. Anthony serves as a lead partner in the glyphosate litigation where he manages litigation pending in jurisdictions throughout the United States. He is also litigating a mass toxic tort action involving alleged exposure to radiation where he has been involved in every aspect of the litigation, including developing expert testimony regarding medical causation, source term, air modeling and dose reconstruction.  Anthony is also actively litigating several cases throughout the U.S. involving alleged contamination and exposure to PFOA and PFAS.  

Through this practice, Anthony has gained knowledge in OSHA and EPA regulations as well as NIOSH and ACGIH exposure limits and history. Further, Anthony has developed expert and company witness testimony regarding the sufficiency of the MSDS or SDSs for products supplied or manufactured by clients. Anthony has been part of a trial team that successfully defended a $36.5 million wrongful death and premises liability suit on behalf of a utility company whose power plants had asbestos-insulated pipes dating back to the 1950s. He prepared direct and cross-examination outlines, opening and closing statement outlines, prepared the defense’s sole expert witness and one of two corporate witnesses for trial.

Anthony also worked on a mass toxic tort action by hundreds of employees of a closed muffler plant involving alleged occupational exposure to formaldehyde. He was involved in all facets of the litigation, including preparing experts and corporate representatives regarding the chemistry of  the product, potential exposure in the plant, and compliance with OSHA’s Hazard Communication Standard.


Anthony regularly works on mass nuisance cases involving many plaintiffs. For example, he represented a Fortune 500 company in a nuisance matter involving two poultry farms in which more than 50 residents of a small town alleged that odor from poultry farms was a nuisance and trespass. The cases were severed into bellwether trials. After numerous depositions, motion practice and expert discovery, the plaintiffs’ sole damages expert was excluded and the case was resolved under very favorable terms for the client.

In addition to odor nuisance cases, Anthony has worked on nuisance actions based on waste from a juice plant’s operation that allegedly contaminated nearby groundwater and damaged their property; nuisance actions based on wastes and operations from energy operations; and nuisance actions involving alleged exposure to sewage contaminants. Anthony prepared expert witnesses, deposed plaintiffs and drafted motions for summary judgments, Daubert motions and motions in limine that led to the successful resolution of a case involving alleged natural resource damages, subsidence and nuisance claims against a mining company for past mining activities.


In addition to Anthony’s expertise in the occupational exposure field, he has also counseled clients regarding OSHA inspections and fines. Anthony has counseled clients regarding proper environmental, health and safety programs and helped clients obtain successful resolutions after OSHA fines. Anthony has counseled clients regarding COVID-19 OSHA-related issues.
