Aaron M. Levin focuses his practice on government contracts litigation before the Government Accountability Office (GAO), U.S. Court of Federal Claims (COFC), Armed Services Board of Contract Appeals (ASBCA), and Small Business Administration (SBA). Bringing a wide range of experience having previously worked for government agencies, he advises companies on all stages of federal acquisitions and government procurements, from solicitation to contract administration, to claims and litigation.

In addition, Aaron assists government contractors with publicly funded contract issues including: mergers and acquisitions; lending; corporate due diligence reviews; federal, state, and municipal ethics and other regulatory requirements; private disputes involving subcontractors; terminations; requests for equitable adjustments and claims; and government investigations. 

Serving as Assistant General Counsel in the Contracts Group of the Office of General Counsel for the United States Department of Defense, Aaron reviewed and advised on federal government contracts to operate and maintain the Pentagon and the Department of Defense’s (DoD) associated facilities. He also identified and addressed government contracting regulatory and compliance issues relating to the Federal Acquisition Regulation and Defense Federal Acquisition Regulation Supplement (FAR/DFARS), cyber, intellectual property (IP), audits, disputes, bid protests, equitable adjustments, investigations, agreements, lawsuits, and claims.

Previously, Aaron served as an Ethics Specialist in the Office of Ethics of the United States Department of Agriculture (USDA), where he advised USDA employees and political appointees on topics raised by the Ethics in Government Act, such as gifts of travel, financial conflicts of interest, misuse of position, appearance issues, the Procurement Integrity Act, the Hatch Act, and lobbying. In this role, he reviewed, certified, and advised on financial disclosure reports to mitigate potential ethics violations. He also prepared and delivered ethics training and drafted agency responses to congressional inquiries, client recusal agreements, and referrals to the Inspector General.
