Beveridge & Diamond, P.C. was established in Washington, DC in 1974 by a small group of attorneys who practiced environmental and corporate law. Since that time, we have become the largest and oldest firm in the nation that concentrates its practice in all aspects of environmental law and litigation. Among the Firm's current attorneys and alumni are the first Administrator of the U.S. Environmental Protection Agency, the first Commissioner of the New York State Department of Environmental Conservation, two former EPA General Counsels, several other former federal and state agency officials, and numerous U.S. Department of Justice attorneys with experience in all types of litigation and contested proceedings.
