Casey is committed to providing legal services that meet his clients’ business goals.

He has a genuine interest in learning about his clients’ operations and is passionate about working in an area of the law that involves a range of industries, complex scientific and technical matters, and delivering solutions that address real-world business concerns.

Casey joined Beveridge & Diamond following tenures as a Law Clerk for United States District Judge Lawrence E. Kahn and U.S. Magistrate Judge Daniel J. Stewart in the U.S. District Court for the Northern District of New York. He uses his experience clerking with both a district and a magistrate judge to handle clients’ needs as creatively and efficiently as possible.

Casey’s environmental litigation and regulatory practice is focused on advising clients nationwide across industrial sectors on issues including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and state Superfund laws. He also has experience with the Endangered Species Act (ESA) and the National Environmental Policy Act (NEPA). He was recognized by AmLaw Litigation Daily for his work in a case in the Southern District of Florida, in which the judge denied class certification in a suit involving 20,000 commercial waste collection customers across the state, having highlighted significant variation in the underlying contracts.

During his time at Harvard Law School, Casey served as a line editor for the Journal of Law and Technology and as a student attorney for the Emmett Environmental Law & Policy Clinic, where his experience included drafting regulations implementing the City of Boston’s Building Energy Disclosure ordinance. He additionally acted as a student advocate for the Tenant Advocacy Project in Cambridge, where he represented public housing tenants at hearings before Boston-area housing authorities.
