Eric’s litigation practice encompasses a broad range of environmental matters, including the prosecution and defense of groundwater and site contamination cases, PCB cost allocations, environmental white-collar defense and internal investigations, and data compensation under FIFRA, the federal pesticide statute. In particular, Eric has defended some of the most significant environmental citizen suits filed in recent times, including the successful resolution of a $4 trillion Clean Water Act citizen suit filed against a major U.S. transportation company.

As a second-year law student, Eric argued before U.S. Supreme Court Justice Samuel Alito, who recognized Eric with "Best Oralist" and "Best Brief" awards. Following law school, Eric clerked for the Honorable Robert I. Richter at the Superior Court of the District of Columbia. He also serves as co-chair of B&D’s Pro Bono Committee and maintains an active pro bono practice, specializing in defending tenants in eviction actions. 

Eric’s life outside the law mostly involves building furniture, playing the occasional game of chess, and singing Disney songs with his daughter. Additionally, throughout his career, Eric has worked consistently to maintain side jobs as a teacher in some form. For many years, he was a Professorial Lecturer in Law at The George Washington University Law School, teaching appellate and trial advocacy. He also taught chess to elementary and middle school students at the KIPP AIM Academy and served on the Advisory Board of Chess Challenge in D.C.; a nonprofit focused on academic achievement through chess instruction.
