Marc T. Napolitana, an Associate in Tully Rinckey PLLC’s Washington, D.C. office, practices in support of clients needing representation in Military Law and National Security Law. Marc brings his extensive legal experience to Tully Rinckey from the U.S. Marine Corps Defense Services Organization (National Capital Region) and two private law firms. His extensive experience handling security clearance review triggers with respect to personal conduct, alcohol, drugs, financial considerations, criminal conduct, handling of classified information, and misuse of information systems will augment the firm’s security clearance representation expertise.

Prior to joining Tully Rinckey, Marc spent his entire legal career on active duty in the U.S. Marine Corps as a defense counsel. He was selected for the Marine Corps Advance Trial Advocacy Competition at American University in Washington D.C. In 2018, he was named the “Defense Counsel of the Year” for the United States Marine Corps (National Capital Region) and he was assigned as the Training Officer for all attorneys and enlisted staff in the Marine Corps Defense Services Organization (National Capital Region) on topics such as advocacy, litigation and military justice.

He has successfully defended Marines in contested criminal trials who were acquitted of serious charges, including attempted murder, maiming, sexual assault, aggravated assault, wrongful use of a controlled substance and driving under the influence. He has served as first chair counsel on more than 75 administrative separation boards and boards of inquiry, where Marines and Sailors were facing discharge from the Naval Service. Marc also has prepared multiple expert witnesses to testify at motions hearings and for trial, and conducted direct and cross examinations of expert witnesses at trial and in administrative hearings. Additionally, Marc has litigated numerous motions before general and special courts-martial to include guilty pleas, motions to suppress evidence, motions to compel discovery, motions to limit the scope of expected testimony, motions to compel expert witnesses, motion to declare witnesses incompetent to testify, and many more issues relevant to trial. He has conducted investigations and contested hearings for clients in dozens of cities and states across America and in Germany.

Prior, as a Law Clerk at two private law firms, Marc conducted legal research and case preparation for more than 50 criminal defense and personal injury cases, and investigated those cases alongside a full-time investigator by making site visits, reviewing evidence, analyzing police video footage and conducting witness interviews. He also conducted legal research and legal writing on more than 10 cases involving complex issues in insurance, employment, premises liability and construction law, with an eye toward preparing the material for litigation. Additionally, he drafted interrogatories, assisted in civil document review and reviewed numerous depositions involving expert witnesses. Marc previously worked as an Advanced Technologies Intern for Raytheon Company, where he coordinated the contract closeouts process for Raytheon contracts with expired periods of performance and prepared contract closeout notifications and proprietary information agreements with both government and commercial customers.

Marc obtained his law degree from the University of Tennessee College of Law, where he was the Chair of the Sports & Entertainment Law Society and named the Distinguished Clinical Student for the Homer A. Jones, Jr. Wills Clinic. He earned a Bachelor of Arts degree in Communications with a Minor in American Studies from Boston College. Prior to that, he graduated Officer Candidates School as Platoon Commander.
