Arnold P. Casterline

Arnold P. Casterline serves as a key procurement lead within the Detention Compliance and Removals unit of U.S. Immigration and Customs Enforcement, overseeing the acquisition of mission-critical services that support secure detention operations and removal logistics. His responsibilities include managing the full lifecycle of contracts for security, facility support, and operational services essential to the agency’s compliance and enforcement objectives. He routinely handles complex procurements under FAR Part 13 and Part 15, with a focus on performance-based requirements that ensure detainee safety, facility integrity, and regulatory adherence across federal detention sites. Casterline maintains enduring relationships with core contractors including B.I. Incorporated, Acentra Health LLC, and Ardent Group, LLC, which provide specialized security systems, medical support, and detention facility services. His contracting approach emphasizes vendor reliability, compliance with DHS standards, and scalability to meet fluctuating operational demands. He consistently engages with vendors capable of delivering integrated solutions across physical security, health services, and logistical support, fostering long-term partnerships grounded in performance metrics and accountability. His procurement portfolio reflects a balanced commitment to socioeconomic goals, with approximately one-third of awards designated for small business set-asides—equally split between Total Small Business and 8(a) competed contracts. While the majority of acquisitions remain open to all competitors, his consistent use of 8(a) programs demonstrates a deliberate strategy to expand opportunities for disadvantaged businesses while maintaining operational readiness. Casterline’s primary procurement focus lies in NAICS 561621 (Security Systems Services) and 561612 (Security Guards and Patrol Services), with significant activity in facilities support, solid waste collection, and building equipment contracting. His expertise centers on securing integrated operational environments that combine surveillance technology, personnel services, and infrastructure maintenance to sustain compliant and humane detention operations under DHS mandates.
