Biography

After more than a decade of public service, Sean Moriarty has returned to the Archer family as a member of Archer Public Affairs.

As the most recent past Deputy Commissioner of the New Jersey Department of Environmental Protection (NJDEP), Sean oversaw an organization of more than 3,000 environmental professionals, leading NJDEP’s internal legal team, guiding the department’s legislative strategy, overseeing transactions, land acquisition and administration and developing a cohesive enforcement policy. In addition to his expansive leadership responsibilities, Sean also played a critical role in providing practical and strategic guidance in the development and implementation of nearly all of NJDEP’s key policy initiatives including land use reform, clean energy policy, natural resource protection, green acres acquisition and development, funding prioritization, remediation, enforcement and program development – often acting as a thought leader and policy advocate in public settings across the county. Perhaps most notably, Sean was the primary architect of New Jersey’s first-in-the-nation Environmental Justice regulatory program.

Prior to being appointed Deputy Commissioner, Sean served in various environmentally-focused roles with the State. Before joining NJDEP in 2017, Sean served as Deputy Attorney General in the Office of the Attorney General for the New Jersey Division of Law, where he provided day-to-day general counsel to various levels of client agency on issues ranging from regulatory compliance and reform, land acquisition, contracting and appellate defense. Upon joining the department, he first served as a Green Acres compliance officer before being promoted to oversee all rulemaking as the Director of the Department’s Office of Legal Affairs and again to the position of Chief Advisor for Regulatory and Legislative Affairs. All told, Sean’s influenced nearly every aspect of the State’s environmental regulatory apparatus.  

As a strategic advisor and consultant, Sean better understands complex government systems and policymaker mindsets to help tailor his clients’ plans to most efficiently and effectively achieve their business objectives. Whether leading or in support of a team, his experience in both the government and private sector gives him a unique perspective on a wide range of complex issues. Respected by all sides for his thoughtful, practical analysis of issues and strategy development, Sean’s focus is on assisting private and public sector clients with concerns rooted in environmental justice, public policy, legislative development and analysis, regulatory strategy, stakeholder engagement, resource sustainability and resilience, land use, green acres, solid waste, remediation, natural resources and clean energy.

Sean received his J.D. from Rutgers University School of Law and his B.S., Management Science and Information Systems from Rutgers College.
