Jennifer focuses her practice primarily on environmental litigation, with specialties in defensive litigation and large-scale discovery. Jennifer works with clients on some of the highest profile, most sensitive matters, providing both legal counsel and end-to-end strategic advice. She is the recipient of multiple Environmental Protection Agency (EPA) and Department of Justice awards for excellence in conduct of litigation and all phases of discovery. This includes a nomination for the Samuel J. Heyman Service to America Medal in 2015 for her unique innovation and leadership role in developing the Agency’s eDiscovery program.

As a seven-year veteran of the United States Environmental Protection Agency, Jennifer brings expertise in information governance, eDiscovery, and best practices for complex litigation. At the EPA, Jennifer was the lead attorney for over 30 cases, defending the Agency against claims brought under the Freedom of Information Act, the Federal Rules of Civil Procedure, the Privacy Act of 1974, and the Federal Records Act. Jennifer’s environmental litigation experience includes heading EPA’s discovery team in the Agency’s biggest and most complex enforcement and defensive matters, including the Volkswagen AG Clean Air Act enforcement litigation, the Gold King Mine release multidistrict litigation, and the Diamond Alkali Superfund Site in the Lower Passaic River area in New Jersey, as well as numerous smaller actions.

Jennifer was a highly regarded speaker and trainer at EPA, frequently called upon to train legal and technical staff nationwide on best practices for complex litigation and large-scale discovery. As an adjunct professor, Jennifer instructed a popular and comprehensive environmental law survey course at Baltimore County Community College, including units on the Clean Air Act, the Clean Water Act, CERCLA, RCRA, EPCRA, TSCA, FIFRA, NEPA, and administrative law and procedure. Many of Jennifer’s courses and trainings were offered for Continuing Legal Education credit in multiple states, such as New York and Illinois, and she continually updates her courses to account for the many recent changes to both environmental law and discovery practice such as the Frank R. Lautenberg Chemical Safety for the 21st Century Act (amending TSCA) and the 2015 Amendments to the Federal Rules of Civil Procedure.

During law school, Jennifer interned for The Honorable District Judge Jose E. Martinez, Southern District of Florida. Jennifer served as the student editor of the University of Miami Law Review online journal JOTWELL (A Journal of Things We Like Lots) and was the winner of the Pace Environmental Law Competition Best Brief in Spring 2011. Before attending law school, Jennifer served as a Peace Corps volunteer in Ixchiguan, Guatemala, working as a project manager for the Technology and Family Health project, which built gravity-based water systems, rainwater catchment systems, and woodstoves in rural areas of Guatemala. Jennifer graduated summa cum laude, Order of the Coif, from University of Miami School of Law in 2011.
