Arnold P. Casterline

Arnold P. Casterline serves as a Contract Specialist within the Detention Compliance and Removals unit of U.S. Immigration and Customs Enforcement, where he manages the acquisition lifecycle for critical operational support services essential to immigration detention and removal operations. His responsibilities include developing solicitation documents, conducting market research, evaluating proposals, and administering contracts aligned with FAR guidelines to ensure compliance, security, and efficiency in detention facility management. He routinely handles service-based acquisitions spanning security, healthcare logistics, and professional technical services, ensuring alignment with DHS mission priorities for detainee care and facility oversight. Casterline maintains consistent working relationships with key contractors including B.I. Incorporated, Acentra Health LLC, and Ardent Group, LLC, which provide specialized detention support, medical services, and operational consulting. His procurement approach emphasizes performance-based contracting and long-term vendor partnerships, fostering accountability through clear statement of work definitions and robust contract monitoring. These relationships reflect a preference for established vendors with demonstrated experience in federal detention environments and compliance with ICE operational standards. While the majority of his acquisitions are conducted without set-asides, Casterline consistently allocates approximately 25% of contract opportunities to Total Small Business Set-Asides under FAR 19.5, reflecting a deliberate commitment to expanding small business participation. He does not routinely utilize 8(a), HUBZone, or SDVOSB set-asides, instead prioritizing broad small business eligibility to enhance competition and innovation within the contractor base. His primary procurement focus lies in NAICS 561612 for security guards and patrol services, which constitutes half of his portfolio, followed by NAICS 311991 for perishable food manufacturing to support detainee nutrition programs and NAICS 541990 for professional technical services including compliance auditing and operational analysis. This technical domain expertise underscores his specialization in mission-critical, non-lethal support services under high-stakes federal detention environments.
