Daniel Rottenberg provides strategic counsel and legal services to clients on a wide range of complex matters involving environmental, toxic tort, and administrative law.

Clients turn to Daniel for his extensive experience in the environmental sector, particularly in litigation, enforcement-related issues, regulatory development, internal investigations, and crisis management. He brings deep statutory and regulatory expertise across the federal environmental framework, including the Clean Air Act, the Clean Water Act, CERCLA, RCRA, the Safe Drinking Water Act, which he leverages to develop strategic positions in high-stakes mass tort and enforcement matters.

Daniel is particularly active on issues related to emerging contaminants, including PFAS and ethylene oxide, and has worked on high-profile emerging contaminant matters in both the public and private sectors.

Daniel’s practice includes representing a leading global diversified manufacturer in PFAS enforcement and related mass tort litigation across multiple jurisdictions, including major state attorney general enforcement actions with claims for remediation, natural resource damages, property damage, and diminution in value. Daniel litigates individual matters through discovery and expert disclosures, and he coordinates expert work across the client’s PFAS docket, including natural resource damage, air dispersion modeling, and property valuation and diminution in value experts whose analyses must remain aligned across cases and jurisdictions.

Prior to joining Jenner & Block, Daniel served on the team representing a major telecommunications company in the Maui wildfire litigation, where he litigated individual cases into discovery and expert reports and assisted in negotiating the multi-billion-dollar global settlement that resolved the litigation. He also coordinated and litigated hundreds of cases involving ethylene oxide emissions in private practice, drawing on expertise in the chemical that he first developed while managing a high-profile ethylene oxide matter at the Illinois Attorney General's Office.
