Airman Sierra M. Caselle

Airman Sierra M. Caselle supports mission-critical procurement operations within the FA3016 502 Contracting Clinic under the Department of the Air Force, facilitating the acquisition of specialized services essential to installation readiness and operational sustainability. Responsible for managing complex contracting actions across medical, facility, and communications domains, Caselle ensures compliance with federal acquisition regulations while aligning procurements with the Air Force’s strategic priorities in infrastructure modernization and force protection. Their portfolio primarily includes service-based contracts for maintenance, technical support, and health-related systems, requiring precise application of FAR and DFARS guidelines to meet urgent operational needs. Caselle maintains consistent working relationships with a core group of contractors including PERRY MANAGEMENT CORP OF SOUTH DAKOTA, L.L.C., WILLIAM T BROOKS & ASSOCIATES INC, CITADEL FEDERAL SOLUTIONS LLC, NEXLEGACY LLC, and AJ COMMERCIAL SERVICES, INC. These vendors are frequently engaged for facility maintenance, communications infrastructure support, and ambulatory health services, reflecting a preference for experienced, mission-aligned partners with proven performance in DoD environments. The contracting pattern demonstrates reliance on established vendors with demonstrated capability in delivering high-reliability services under time-sensitive conditions. Set-aside preferences are heavily weighted toward unrestricted competition, with 87.5% of awards issued without socioeconomic set-asides, indicating a focus on full and open competition to ensure optimal value and capability. However, a consistent 12.5% of awards are designated as Total Small Business Set-Asides under FAR 19.5, demonstrating a measured but deliberate commitment to small business participation without compromising mission requirements. Caselle’s procurement focus centers on NAICS 511210 (Software Publishers), 541519 (Other Computer Related Services), 621999 (Miscellaneous Ambulatory Health Care Services), 334118 (Computer Peripheral Equipment), and 334510 (Electromedical Apparatus). This reflects deep technical expertise in procuring integrated medical systems, digital communications infrastructure, and facility-support technologies critical to sustaining Air Force operational environments.
