Susan B Mielke

Susan B. Mielke serves as a key procurement professional within the Transportation Security Administration’s Mission Essentials unit, supporting the agency’s mission to enhance operational readiness through facility-based training infrastructure. She manages acquisitions focused on safety-critical training environments, including firing range services, tactical equipment, and related facility operations. Her work ensures federal law enforcement and security personnel maintain high standards of weapons proficiency and operational safety, aligning procurement activities with DHS strategic priorities. Mielke typically handles complex service and facility-related contracts requiring compliance with federal safety and security standards, often coordinating with technical specialists to validate performance requirements. Her contractor relationships center on vendors providing specialized training infrastructure, including nonresidential facility lessors, safety equipment suppliers, and technical service providers. She collaborates with a mix of large-capacity contractors and small businesses capable of delivering secure, compliant, and mission-tailored solutions. While no single vendor dominates her portfolio, her procurement patterns reflect a preference for vendors with demonstrated experience in federal security environments and proven track records in maintaining high-safety operational standards. Mielke’s contracting approach prioritizes broad market access, with approximately 84% of awards issued as open competitions. She maintains a consistent, though modest, commitment to small business participation, with 13% of awards designated for total small business set-asides and 3.2% reserved for service-disabled veteran-owned small businesses. Her socioeconomic strategy supports competitive bidding while ensuring opportunities for qualified disadvantaged and veteran-owned firms, aligning with FAR 19.5 and broader DHS small business goals. Her primary NAICS focus includes nonresidential building lessors for training facilities, computer and software wholesale distribution for training systems, and specialized technical services such as court reporting and IT support. These reflect a technical domain centered on secure, scalable, and compliant training environments, where Mielke applies deep expertise in facility-based procurement, safety compliance, and mission-critical service acquisition.
