Nick also assists companies with trade compliance assessments and internal investigations, voluntary disclosures, licensing, and export classification.

While in law school, Nick clerked at the Office of the United States Attorney and worked for Hon. Timothy M. Tymkovich and Hon. Neil M. Gorsuch, both of the U.S. Court of Appeals for the Tenth Circuit. Prior to his legal career, Nick was an officer and paratrooper in the United States Army, serving as a U.S. Army Ranger and an airborne jumpmaster.
