Our Law Firm

          Founded in 2003, McAdoo Gordon & Associates, P.C. primarily represents clients who have a case with the government as their opponent. 


          Whether it's an agency denying clearance, an OIG, law enforcement or Congress investigating, an agency trying to debar from government contracts, a state bar contemplating discipline, a prosecutor proposing criminal charges, an agency threatening discipline - or several of these at once - our proto-typical client is a military member, a government employee, a government contractor (people and companies), or a lawyer facing the incredible power of the government to take serious action against them. 

          With over 20 years of experience in these matters, we use our intellect, skill, and tenacity to put together the best plan for handling these important - often life-altering -  matters to get the best result possible for each client.
