He has served in several of our Nation’s most elite units, where he supported critical intelligence and special operations initiatives that have had a lasting impact both domestically and globally.

In his current role, he leverages the extensive expertise gained across the Department of Defense, Intelligence Community, and internationally to support North Carolina constituents in the national security space, as well as the Senator’s role in key bipartisan efforts such as the Senate NATO Observers Group and the Senate Taiwan Caucus.

Mr. Lintzenich has held influential strategic roles that underscore his ability to navigate complex policy and defense issues at the national level.
