Federal contractors of all sizes look to Dave Yang for his strategic counsel in navigating all phases of the federal procurement process. Drawing on his decade’s long experience of the state, local and federal marketplaces, Dave regularly advises clients on all critical aspects of their business, whether the issues involve compliance, intellectual property, prime-subcontractor matters, cost accounting, claims, bid protests or other disputes.

Dave also regularly litigates on behalf of contractors before a diverse range of government forums and in arbitrations before the American Arbitration Association. Dave focuses on bid protests, where he has successfully protested and defended billions of dollars’ worth of some of the largest defense and civilian procurements in recent history before the U.S. Government Accountability Office and the U.S. Court of Federal Claims, where he served as a law clerk early on in his career.  In addition to his expansive protest work, Dave has recovered millions of dollars in Contract Disputes Act claims before the boards of contract appeals and also routinely defends contractors in False Claims Act cases in federal courts nationwide.  Dave has strategically obtained dismissal of several multimillion-dollar FCA lawsuits through the effective and efficient use of pre-trial motions.

Most recently, Dave was a partner at an AmLaw 100 firm in Washington, D.C. He served as a law clerk for the Honorable Mary Ellen Coster Williams at the U.S. Court of Federal Claims in 2004.
