Justin Geisendaffer

Justin Geisendaffer serves as the primary contracting lead within the U.S. Coast Guard’s Headquarters Contract Operations (CG-912), where he oversees strategic acquisitions critical to national maritime security and operational readiness. He manages a diverse portfolio of contracts spanning vessel construction, maritime system modernization, and technical services essential to enhancing coastal patrol capabilities and maritime domain awareness. His work directly supports the Coast Guard’s mission to sustain and expand its fleet infrastructure through new construction, life-cycle upgrades, and specialized engineering solutions. Geisendaffer handles complex, high-priority procurements under FAR Part 13 and Part 15, often involving multi-year, performance-based contracts for mission-critical assets. He maintains longstanding relationships with key shipbuilders and maritime system integrators, including Bollinger Shipyards, Davie Defense Inc., Rauma Marine Constructions Oy, and Rozema’s Boat Works, Inc. These partnerships reflect a focus on proven vendors with specialized expertise in aluminum and steel vessel fabrication, naval architecture, and integrated sensor systems. His contracting approach emphasizes vendor reliability, technical capability, and past performance, fostering collaborative, long-term engagements rather than transactional procurement cycles. Geisendaffer’s contracting patterns show a strong preference for open competition, with 87.5% of awards issued without set-asides. However, he consistently allocates 12.5% of opportunities to Total Small Business Set-Asides under FAR 19.5, demonstrating a measured but deliberate commitment to small business participation without compromising mission-critical requirements. His approach balances regulatory compliance with operational urgency, ensuring small businesses contribute meaningfully to the Coast Guard’s modernization goals. His primary procurement focus lies in NAICS 488310 (Port and Harbor Operations) and 483111 (Deep Sea Freight Transportation), reflecting his role in sustaining maritime logistics infrastructure. He also frequently procures services under 336612 (Boat Building) and 541330 (Engineering Services), underscoring his technical expertise in naval vessel design, marine systems integration, and lifecycle support for specialized Coast Guard assets.
