Andrew Gillman

Practice Areas:

Andy is a broadly experienced contracts and general legal expert. He offers candid and experienced legal advice, seeking swift and amicable resolution for busy clients and government offices wherever possible, but fully ready for carefully reasoned and methodically executed litigation where necessary. Andy recently retired from active military service. During his time in the military, he advised joint and coalition forces around the world in support of national and international priorities. 

Contracts Experience

Andy understands the business and legal challenges that contractors face every day. He has drafted or reviewed over 1,000 federal government contract actions for issues and acquisitions arising under nearly every corner of government contract and fiscal law. These contracts included services, supplies, construction, architect and engineering, research and development, information technology, specialized advisory/assistance services, bid protests, terminations, debarments, and many other unique or specialized situations. Early on in his career, he worked as an independent contractor (database programmer) supporting small businesses and academic research. After receiving his officer’s commission, he served three years as a negotiator and contingency contracting officer, first at installation level and then an aircraft systems procurement office, eventually managing government contracts valued at nearly $1 billion. After completing his studies at Harvard Law School, Andy served as a legal advisor (judge advocate) for 15 years. He is intimately familiar with small and large business compliance requirements, commercial and non-commercial acquisitions, full and open competition and set-aside methodologies, all types of price and cost contracts and line items, ordering arrangements and agreements such as IDIQ and BPA, the many varieties of appropriated and non-appropriated funds, and unclassified and classified contract requirements in both domestic and international settings. 


Andy can help you see legal challenges from many perspectives. He has advised on criminal investigations and prosecutions for fraud, embezzlement, false claims, false statements, and similar allegations of contract or financial crimes. He served as counsel or provided significant advice, as a military prosecutor and later at senior command levels, on numerous courts-martial including litigated murder, sexual assault, and other serious cases. He was also a Special Assistant United States Attorney in two separate jurisdictions. In addition, Andy oversaw legal assistance and tax return preparation programs and personally prepared hundreds of wills and testamentary trusts as well as providing free legal consultation to servicemembers, retirees, and families to resolve their personal challenges. He worked as a claims and supervisory claims officer, reviewing and settling Federal Tort Claims Act, Military Claims Act, and other claims against the government. He also served as an associate professor of international and operational law for masters degree and short course instruction, teaching over 2,000 military commanders and government attorneys, and co-editing three U.S. Armed Forces legal handbooks. He collaborated on various interagency and inter-governmental efforts; and consulted regularly on ethics compliance, security investigations, audits, and innumerable other government concerns. For many years Andy was also stationed abroad, advising senior commanders and staffs in the Middle East, Africa, the Pacific, and Europe responsible for tens or hundreds of thousands of servicemembers, civil servants, contractors, and family members.


More broadly, Andy can help you understand government decision-making. He served as counsel or advised on extraordinarily complex matters, to include investigations involving hundreds of complaints, capture and extradition of an internationally indicted war criminal as well as FBI most wanted terrorists, an active shooter scenario, national military support to embassy evacuations and two international pandemics (Ebola and COVID), natural disaster response, air policing, air defense identification zones, rules of engagement, multi-domain operations, and other sensitive duties. He advised joint, combined, and coalition forces, helping to integrate efforts from all six branches of the U.S. Armed Forces around the globe, on real-world operations in air, space, cyberspace, land, and maritime settings. He also worked with allied and partner nations on mutual endeavors, including as a senior legal officer and command advisor, posted on exchange with the United Kingdom’s Royal Air Force. Many of Andy’s duties required preparing advice for decisions by senior military and civilian officials on sensitive issues of national and international importance.
