Kegan A. Brown represents clients in the full lifecycle of complex environmental and products liability litigations and regulatory matters, particularly involving per- and polyfluoroalkyl substances (PFAS) or natural resource damages.

Mr. Brown helps companies navigate all aspects of litigation and regulatory risks relating to their potential involvement with PFAS or other emerging contaminants by:

He leverages extensive experience and a commercial perspective to reduce clients’ current and future potential liability exposure and to identify cost-effective mitigation efforts that align with their ESG sustainability objectives. Mr. Brown also advises buyers, sellers, lenders, and underwriters on a broad range of environmental issues in mergers, acquisitions, and financing transactions.
