BakerHostetler adds partner Adam Baas to San Francisco Environmental and Product Liability teams
"Adam Baas has joined BakerHostetler in San Francisco as a partner, joining the Environmental and Product Liability and Toxic Tort teams to handle emerging contaminants, PFAS, product liability and environmental litigation."
Baas brings more than two decades of experience in high-stakes toxic tort, product liability and environmental litigation, as well as environmental compliance and enforcement counseling and defense. He is one of the country’s leading emerging contaminants litigators, with over a decade of experience handling PFAS-related matters and other contaminants including ethylene oxide, 6PPD and dioxin.
Throughout his career Baas has represented corporate clients as lead counsel in complex multi-plaintiff matters, locally managed mass torts in state courts and national multidistrict litigation in federal courts. He has defended actions alleging PFAS contamination and exposure in state and federal courts, including multidistrict litigation and putative class actions, and recently completed a federal trial concerning the use of 6PPD in tires. Baas’s practice also encompasses state attorneys general actions seeking natural resource damages, defenses to citizen suits under environmental laws, and collaboration with experts in toxicology, chemistry, hydrology and epidemiology.
In addition to litigation, Baas advises clients on regulatory compliance with state and federal environmental laws, remediation and transactions involving contaminated properties, negotiating access agreements and reviewing environmental aspects of real estate transactions. He received his J.D. from Boston University School of Law and a B.A. from the University of Oregon.
Baas joins BakerHostetler from an Am Law 10 firm.
