Washington, DC - We are pleased to announce the expansion of our Natural Resources and Project Development practice with the arrival of John G. Cossa, who has joined the Firm as an Associate in our Washington, DC office. Mr. Cossa most recently served as an Attorney-Advisor at the U.S. Department of the Interior’s (DOI) Office of the Solicitor, after joining the Department as a Presidential Management Fellow.  While at the Solicitor’s Office, Mr. Cossa was lead counsel for the Bureau of Ocean Energy Management’s (BOEM) offshore renewable energy program, and also provided legal advice to the Department’s offshore and onshore oil and gas programs.  Prior to joining the Solicitor’s Office, Mr. Cossa served as advisor to the Assistant Secretary for Land and Minerals Management on Bureau of Land Management energy and land use issues. 

Mr. Cossa’s practice focuses on issues related to the development of energy and mineral resources on federally-managed lands.  He advises clients on matters related to the leasing and development of oil and gas, wind, solar, and mineral resources both onshore and on the Outer Continental Shelf.  

“John is a wonderful addition to the Firm.  His experience with DOI energy, regulatory, and environmental programs will provide great value to our clients,” said Peter Schaumberg, Co-Chair of the Firm’s Natural Resources and Project Development practice and former DOI Deputy Associate Solicitor for Mineral Resources. 

During his DOI tenure, Mr. Cossa received the Secretary’s Commendation for Outstanding Service for his role in implementing the U.S. offshore renewable energy leasing program.  He also received the Solicitor’s Excellence Award in 2011 for outstanding contributions in the wake of the Deepwater Horizon oil spill. 

Mr. Cossa, 39, is a graduate of Syracuse University and a former art dealer.  He received his J.D. in 2007 from American University’s Washington College of Law.
