John S. Hahn

For over 40 years, John Hahn's practice has encompassed a variety of high-stakes environmental counseling and litigation matters. These have involved defense against federal and state enforcement actions and challenges to rulemaking authority, as well as private-sector disputes over contaminated sites and issues of successor liability. He has extensive experience with challenges to real estate development and the allocation of environmental liabilities in corporate and real estate transactions. John is recognized by Chambers USA for Environmental Law. In Chambers USA 2018, sources describe him as “"'[e]xtremely knowledgeable and hardworking[,]' and say [he] is a 'tireless negotiator' who regularly defends clients in enforcement actions."
