Jennifer focuses her practice primarily on complex environmental litigation, including large-scale discovery. Jennifer works with clients on high profile, sensitive matters, providing both legal counsel and end-to-end strategic advice to bring even the most difficult cases to successful resolution. A seven-year veteran of the United States Environmental Protection Agency’s (EPA’s) Office of General Counsel, Jennifer received multiple EPA and Department of Justice awards for excellence throughout all phases of litigation. 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 entire eDiscovery program.

Jennifer brings expertise in environmental law, as well as information governance, eDiscovery, and best practices for complex litigation. As the lead EPA attorney for over 30 cases, she defended 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.

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, including units on the Clean Air Act, the Clean Water Act, CERCLA, RCRA, EPCRA, TSCA, FIFRA, NEPA, the ESA, and administrative law and procedure. Jennifer’s courses and trainings also provided Continuing Legal Education credit in multiple states.

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 and won the Pace Environmental Law Competition Best Brief in Spring 2011. Before law school, Jennifer served as a Peace Corps volunteer in Ixchiguan, Guatemala, working as a project manager for the Technology and Family Health project to build gravity-based water systems, rainwater catchment systems, and woodstoves in rural areas.
