Mark A. Amadeo


Mark has served as outside counsel to Fortune 200, medium, small, and non-profit companies, local government entities, and government contractors. A skilled advocate who has vigorously pursued and defended claims on behalf of clients in federal and state courts throughout the country, Mark offers a unique litigation perspective that helps government contracting clients avoid traps and pitfalls that can lead to time-consuming and expensive litigation. Mark has leveraged his extensive litigation background, as well as his transactional experience, to both successfully pursue bid protests against, and to successfully negotiate with, numerous agencies, including U.S. Department of Defense agencies such as Army, Navy, and the Missile Defense Agency.

Mark has also helped government contracting clients manage their relationships with other contractors through the use of carefully crafted teaming agreements, subcontracting agreements, joint venture agreements, nondisclosure agreements, and other instruments. Mark has written on the subject of pursuing federal government contracts with joint ventures and on the use of technical data and computer software in federal government contracts, and has given presentations on a variety of government contracting issues, including state and federal certifications, the U.S. Small Business Administration’s mentor-protégé programs, tribally-owned 8(a) companies, and the federal government’s Small Business Innovation Research and Small Business Technology Transfer Research Programs. 

Mark is a member of the bar in Maryland, Wisconsin, New Jersey, and the District of Columbia, and is admitted to practice in state and federal courts in those jurisdictions.
