Jeffery M. Chiow, Co-Chair of Greenberg Traurig's Government Contracts Practice, represents clients in litigation and government investigations related to government contracts, including federal and state bid protests and claims. Many of the bid protests that he litigates involve enterprise critical matters with billions of dollars at stake. Jeff has deep experience in the aerospace and defense sectors, as well as cybersecurity, technology services contracting, and schedule contracting. Prior to entering private practice, he was a U.S. Marine Corps weapons and sensors officer in the F/A-18D Hornet. This experience informs Jeff’s work with cutting-edge technology in the areas of space systems, cloud computing, weapons platforms and IT systems. Jeff also advises businesses on compliance matters, working with government contractors to develop tailored strategies for addressing complex business, legal, and regulatory issues. In particular, he is a recognized leader in the constantly-evolving area of cybersecurity, including compliance with DoD’s cyber and supply chain requirements and the CMMC initiative and related investigations and disclosures. 

Jeff’s False Claims Act experience includes advising on alleged fraud involving federal grants, DOJ Civil Fraud investigations, and qui tam suits alleging hundreds of millions of dollars in damages. He conducts sensitive internal compliance investigations and counsels defense, health care, construction, and technology clients about potential civil and criminal liability as well as potential disclosure obligations.
