Jimmy is a trial and appellate lawyer with decades of experience in federal and state courts across the country. He represents companies, public agencies, trade associations, and municipalities in environmental, tort, constitutional, and commercial disputes. He litigates to win and deter opponents from suing his clients. For years, Chambers has recognized Jimmy for his litigation practice, with clients describing him as "one of the most gifted attorneys I've met” who is "focused on delivering excellent client service."

Jimmy’s many courtroom wins led to Law360 naming him an Environmental “MVP” in 2020 and American Lawyer selecting him as a Runner-Up for Litigator of the Week five times in 2019, 2020, and 2021, and a Shout-Out recipient in 2023. Recent successes include securing dismissals of citizen suits regarding PFAS, dismissals of class actions in Louisiana and Pennsylvania, and dismissals of class actions in precedent-setting opinions in the New York Appellate Division. He also secured a writ of mandate against Los Angeles County, voiding permit terms for a client’s landfill (saving his clients over $200 million), and a federal preemption of a Baltimore air ordinance for a major waste-to-energy facility.

Active in the bar, the District of Columbia Bar Board of Governors in 2026 appointed Jimmy to a three-year term on the Bar’s Legal Ethics Committee, which is responsible for issuing formal ethics opinions for the over 120,000 members of DC Bar. Previously, Jimmy was appointed to three consecutive terms on the DC Bar Rules of Professional Conduct Committee.

Other litigation achievements include securing a unanimous win in the Pennsylvania Supreme Court defeating toxic tort claims, Gilbert v. Synagro Central, 131 A.3d 1 (Pa. 2015) and a judgment for his client the City of Los Angeles after a two week trial on constitutional challenges to a voter initiative banning land application of biosolids, City of Los Angeles v. Kern County, 2017 WL 1292822 (Tulare Co. Cal. Super. Ct. 2017).

Jimmy has tried scores of jury and bench trials and argued cases before many federal and state appellate and trial courts across the country, including the California, Pennsylvania, Virginia, and District of Columbia supreme courts. See, e.g., Cormier v. D.C. WASA, 84 A.3d 492 (D.C. 2013) (trial win and appellate affirmance, defeating tort claims of corrosive drinking water).

A Chambers-ranked lawyer, Jimmy is recognized as a leader in mass tort, class action, and preemption litigation involving solid waste, drinking water, wastewater, and biosolids. He represents waste and recycling companies, cities, farms, contractors, and trade associations in toxic tort, enforcement defense, and complex constitutional and administrative law issues regarding preemption, takings, and the Dormant Commerce Clause. Jimmy is a recognized expert in defending cases related to PFAS and speaks regularly on the topic. He presents at meetings of the American Bar Association (ABA), the National Waste and Recycling Association (NWRA), the Water Environment Federation (WEF), its state affiliates, the American Water Works Association (AWWA), and the National Association of Clean Water Agencies (NACWA). He also works with the country’s top scientists and engineers to defend his clients in courts and before government agencies.

Toxic tort defense is a cornerstone of Jimmy's practice. He defends wrongful death, personal injury, nuisance, and property damage claims involving solid waste, biosolids, drinking water, groundwater, PFAS, and other environmental exposures. He has handled the country’s most significant cases involving alleged public health impacts from land application of biosolids and allegations of lead in drinking water. Jimmy regularly challenges expert testimony under Daubert and Frye. His class action defense experience includes defending cases alleging illegal pricing practices, and he has defeated class certification in federal courts across the country in recent years.

Jimmy is also recognized for his success in federal preemption and Commerce Clause challenges to discriminatory and burdensome local laws. He led a coalition of electronics trade groups and manufacturers in successfully challenging New York City's recycling and product-take-back mandates. He also led the successful constitutional challenge on behalf of the City of Los Angeles to overturn a local ban on the City’s use of its biosolids on California farmland as a fertilizer on Commerce Clause and other constitutional grounds.

Superfund litigation has long been part of Jimmy’s docket, and he has defended and prosecuted CERCLA claims across the country. Jimmy has represented several potentially responsible party (PRP) groups and won a major successor liability ruling in Pfohl Brothers Landfill Site Steering Committee v. Allied Waste, 255 F. Supp. 2d 134 (W.D.N.Y. 2003).

Jimmy joined B&D after serving as an Assistant and Senior Assistant Public Defender in Fairfax County, Virginia. While with the Public Defender's Office, Jimmy successfully defended against a capital murder indictment in Commonwealth v. Reed. Before joining the Public Defender's Office, he clerked for Judge James Sprouse of the U.S. Court of Appeals for the Fourth Circuit.
