Brian P. Theisen

Brian P. Theisen serves as a key contracting professional within the Director of Contracting office under the Department of the Navy, responsible for managing the acquisition of mission-critical defense-enabling services and specialized equipment to sustain operational readiness. His portfolio centers on securing secure computing systems, command-and-control hardware, audiovisual infrastructure, and leased specialized machinery essential to maritime and expeditionary operations. He executes procurements in alignment with DoD acquisition regulations, ensuring timely delivery of capabilities that support deployed forces and modernization initiatives across naval and marine units. Theisen maintains a broad network of vendor partnerships, primarily engaging with manufacturers of telecommunications and computing hardware, as well as firms specializing in equipment leasing and IT services. While no single contractor dominates his award stream, his contracting patterns reflect consistent engagement with firms capable of delivering secure, ruggedized, and interoperable systems compliant with DoD cybersecurity standards. He routinely collaborates with both large-tier defense contractors and niche suppliers offering tailored solutions for naval communications and logistics environments. His procurement approach is overwhelmingly non-set-aside, with 94.1% of awards issued under full and open competition, reflecting a priority for technical capability and mission urgency. However, he consistently allocates 5.9% of opportunities to total small business set-asides under FAR 19.5, demonstrating a measured but deliberate commitment to small business participation without compromising acquisition objectives. Theisen’s primary NAICS focus includes Telephone Apparatus Manufacturing (334210) and Office Machinery and Equipment Rental and Leasing (532420), underscoring his specialization in secure communications hardware and leased technical infrastructure. He also frequently procures other computer-related services (541519) and ordnance accessories (332994), indicating deep expertise in integrating field-deployable electronic systems with sustainment logistics. His technical domain spans secure networking, command-and-control hardware, and mission-critical equipment leasing—critical enablers for naval expeditionary forces.
