Background

About Sean Joyner

The Office of the Solicitor's Branch of Environmental Compliance and Response. Environmental and regulatory attorney with over a decade of experience advising federal agencies on complex matters involving CERCLA, compliance strategy, enforcement, and interagency negotiations. I’ve served as in-house counsel to the U.S. Department of the Interior’s land and resource management bureaus, providing legal guidance on contaminated site cleanup, federal land stewardship, environmental policy, and administrative law. I regularly brief senior decision-makers, coordinate with the Department of Justice, and lead legal strategy on nationally significant sites. I’m passionate about bringing that public-sector insight to collaborative, solutions-oriented work at the intersection of energy, environment, and law.
