Overview

When companies face environmental regulatory enforcement—whether from the U.S. EPA, the DOJ, other government agencies, citizen activist groups, or other private parties—they turn to Kirsten Nathanson as a strategic and pragmatic legal advisor to navigate the myriad risks and drive toward efficient and positive outcomes. In addition to handling litigation encompassing citizen suit defenses; National Environmental Policy Act challenges; CERCLA remediation cost recoveries and defenses; Federal Insecticide, Fungicide, and Rodenticide Act actions; and EPA enforcement, Kirsten’s practice includes a focus on consensus-based dispute resolution and multilateral negotiations and mediation.

Kirsten also serves as a strategic counselor in areas of emerging risk, including climate change; environmental justice; and environmental, social, and governance considerations, particularly when they intersect with all forms of regulatory enforcement and dispute resolution. She supports clients across a range of industries, including energy, agricultural chemicals, and transportation.

Kirsten is co-chair of the firm’s Environmental practice, serves on the firm’s Management Board and Executive Committee, and is co-chair of the board’s Strategic Growth Committee.
