Stacey Geis

Senior Counsel

Overview

Stacey brings over 25 years of experience in environmental compliance as well as civil and criminal enforcement, including as a federal prosecutor and as Deputy Assistant Administrator at the U.S. Environmental Protection Agency, where she helped lead the 2,800-person Office of Enforcement & Compliance Assurance. Before joining EPA, Stacey prosecuted some of the largest environmental cases under the Clean Air Act, Clean Water Act, and federal hazardous waste laws. She has also prosecuted numerous non-environmental white-collar cases, with a focus on corporate fraud and health and safety violations.

Given her government experience, Stacey advises clients facing compliance challenges through the lens of both a regulator and prosecutor. Her practice focuses on compliance planning, incident response, navigating government investigations, enforcement actions, and litigation matters. Stacey also has experience in crisis management, having prosecuted some of the largest U.S. disasters.

Ultimately, Stacey is a problem solver, who uses her broad experience with the EPA, U.S. Department of Justice, state of California, Earthjustice, and in private practice to help clients improve outcomes and minimize potential risks and liabilities both before and after issues develop. Stacey has built strong relationships with her professional connections across local, state, and federal governments to help clients successfully meet their business objectives.

Stacey came to Crowell after having served in the Biden-Harris Administration at EPA. At the Office of Enforcement & Compliance Assurance, she helped implement the Administration’s policy goals, including addressing climate change, PFAS, and revitalization of EPA’s enforcement and compliance programs throughout the country. She also engaged in numerous elevated or high-profile enforcement actions as well as participated in rulemaking, policy, and legal guidance. Most notably, Geis helped create EPA’s Strategic Civil-Criminal Enforcement Policy as well as provided guidance on two recent Supreme Court decisions—Sackett v. EPA, which limited the definition of wetlands under the Clean Water Act; and SEC v. Jarkesy, which limited the scope of federal administrative proceedings.

Throughout her career, Stacey has represented a wide range of clients affected by compliance and enforcement of environmental and public safety laws—including industry stakeholders, communities, the state of California, the United States, and the U.S. EPA. This broad experience has given her deep insight into the needs, concerns, and goals of all parties involved in compliance and enforcement matters, something she brings to her counseling and litigation practice.
