David R. Santimaw

David R. Santimaw serves as a key procurement lead within the Telecommunications Division (HC1013) of the Defense Information Systems Agency, where he manages critical acquisitions to secure and modernize the Department of Defense’s global communications infrastructure. His responsibilities include overseeing the procurement of network services, secure telecommunications systems, and mission-critical IT support solutions that enable resilient, high-capacity connectivity across military and federal operations. Santimaw specializes in complex, technology-driven contracts requiring strict compliance with DoD cybersecurity standards and interoperability requirements, focusing on both legacy system upgrades and next-generation telecom architectures. He maintains consistent partnerships with leading providers including AT&T Technical Services Company, Inc., AOC CONNECT LLC, and Norfolk Fiber, LLC, who deliver end-to-end telecom solutions such as secure virtual private networks, fiber-optic backbone services, and satellite-enabled communications. His contracting patterns reflect a preference for established contractors with proven capabilities in defense-grade infrastructure, while also incorporating specialized vendors with niche expertise in wireless systems and network engineering. These relationships are characterized by long-term, performance-based engagements requiring rigorous technical validation and continuous service assurance. Santimaw’s procurement strategy prioritizes open competition, with 72.2% of awards issued without set-asides, reflecting the mission-critical and highly technical nature of the acquisitions. However, he actively supports small business participation, with 16.7% of awards designated as total small business set-asides and 11.1% allocated to HUBZone firms, demonstrating a balanced commitment to socioeconomic goals without compromising operational readiness. His primary technical focus lies in NAICS 541519 (Other Computer Related Services), encompassing network operations, systems integration, and cybersecurity-enabled telecom support. He also frequently procures satellite telecommunications (517410), engineering services (541330), and wireless communications equipment (334220), underscoring his expertise in the convergence of commercial telecom technologies with defense-grade requirements.
