David Panzer


David Panzer is a Partner at Fluet and serves as the Chair of the firm’s Government Contracts Practice. Mr. Panzer’s practice focuses on high-stakes litigation, government enforcement and challenges to government action. He has particular experience with negotiations, compliance and disputes that have an international component – especially in a contingency environment. With extensive experience as both in-house and outside counsel, Mr. Panzer brings a unique perspective not only to matters to be tried in court but also to the business of law.

Before joining Fluet, he led the Government Contracts Group based in the Washington, DC office of midsize firm, and expanded the practice of Government Contracts boutique in Tysons, VA. Mr. Panzer assembled a team of professionals, with deep industry experience, who design practical business-oriented solutions for their clients’ legal problems.

He previously served as the Deputy General Counsel for a multi-billion-dollar government services contractor that operates around the world. In that role, he managed the day-to-day operations of the Legal Department and was responsible for serving as both the chief advisor on all Government Contracts issues and the lawyer responsible for virtually all significant litigation, investigations, bid protests, Claims and REAs. As a result, he was responsible for negotiating and managing the vast majority of the legal budget and managing the relationships with most of the law firms engaged by the company. During the time that the company was an SEC public filer, Mr. Panzer served as the legal representative on the disclosure committee. As an essential advisor to the C-Suite, he was asked to project-manage the diligence process that led to a successful sale of the company.

Prior to his seven-year stint as in-house counsel, Mr. Panzer spent more than a dozen years at one of the largest law firms in the country (five of which as a partner), where he had a wide-ranging litigation practice.
