Harmon L. (Monty) Cooper is a counsel in Crowell & Moring’s Washington, D.C. office, where he is a member of the Mass Tort, Product, and Consumer Litigation and Environment & Natural Resources groups. 

Monty is both a counselor and trial lawyer, whose practice focuses on product liability, environmental, and complex civil litigation. He has litigated tort and contract cases across the country, advising clients in high-exposure litigation in numerous venues. He has over a decade’s worth of experience in all phases of litigation, from discovery, to motion practice, to trial work (including first-chair jury and bench trial experience), to appellate advocacy.

Monty also advises clients on areas associated with corporate environmental sustainability, including climate change and decarbonization; infrastructure; and environmental, social, and governance (ESG) considerations. He is currently working with a team of Crowell attorneys tracking emerging risks associated with environmental justice issues. Monty also provides counsel on regulatory and legislative matters affecting the mining industry.

Monty has published articles and spoken on panels across the country concerning a wide variety of topics affecting his clients – from environmental and mining matters to changes in the U.S. tax code that affect multinational corporations regarding environmental enforcement to artificial intelligence and digital transformation.

Monty maintains an active pro bono practice, where he has argued criminal appeals before the Maryland Court of Special Appeals and has litigated civil and criminal cases in both Montgomery County (MD) Circuit Court and D.C. Superior Court.
