Sang Han

Sang Han serves as a key procurement lead within the Detention Compliance and Removals unit of U.S. Immigration and Customs Enforcement, supporting the Department of Homeland Security’s mission to ensure safe, secure, and compliant detention and removal operations. Responsible for managing a diverse portfolio of acquisition activities, Han oversees contracts related to facility operations, security services, and logistical support critical to immigration enforcement. Their work ensures that detention centers and transport systems meet federal standards for detainee care, personnel safety, and regulatory compliance, with a focus on mission-critical services that sustain daily operational readiness. Han maintains consistent relationships with core contractors including B.I. Incorporated, Acentra Health LLC, and Ardent Group, LLC, partnering with vendors specializing in security operations, healthcare services for detainees, and facility infrastructure support. These relationships reflect a pattern of sustained engagement with established service providers capable of delivering scalable, compliant solutions across multiple detention sites. The contracting approach emphasizes reliability, regulatory adherence, and operational continuity, with a preference for vendors experienced in federal detention environments. A significant portion of Han’s acquisitions—44.4%—are structured as Total Small Business Set-Asides under FAR 19.5, demonstrating a strong commitment to socioeconomic contracting and small business participation. While no set-aside preferences for 8(a), HUBZone, or SDVOSB programs are dominant, the consistent use of small business set-asides reflects a deliberate strategy to foster competition and expand vendor diversity within the detention support ecosystem. Han’s procurement focus centers on NAICS codes 561612 (security guards and patrol services), 812930 (parking lots and garages), and 321992 (prefabricated wood building manufacturing), indicating expertise in facility infrastructure, perimeter security, and modular construction for detention environments. Additional procurement activity includes food services and temporary lodging, underscoring a holistic approach to managing detainee care and operational logistics across a nationwide network of facilities.
