Samantha Marcellais

Samantha Marcellais serves as the primary procurement lead for the California Indian Health Service, a component of the Indian Health Service within the Department of Health and Human Services. In this role, she manages the acquisition of critical infrastructure, environmental, and operational services essential to sustaining culturally responsive healthcare delivery across remote tribal communities. Her responsibilities include planning, soliciting, and awarding contracts that align with federal Indian health priorities, ensuring compliance with Buy Indian and Indian Small Business Economic Enterprise (ISBEE) statutes. She specializes in facility maintenance, environmental remediation, and technical consulting contracts that support the agency’s mission of resilient, sustainable healthcare infrastructure. Marcellais maintains consistent working relationships with key contractors including WE BUILD LLC and JATCONSULTANTS LLC, both of which provide specialized services in facility systems, logistics, and technical support. Her procurement approach emphasizes long-term vendor partnerships grounded in reliability, cultural competency, and compliance with tribal sovereignty requirements. She frequently engages small and Native-owned firms with demonstrated experience in tribal healthcare environments, fostering trust and continuity in service delivery. Her contracting patterns reflect a strong commitment to socioeconomic set-asides, with nearly half of her awards directed toward Indian-specific programs including ISBEE, Buy Indian, and Indian Economic Enterprise (IEE) set-asides. She also regularly utilizes Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides, demonstrating a deliberate strategy to prioritize historically underserved and mission-aligned small businesses in federal Indian health procurement. Her primary NAICS focus areas include Process, Physical Distribution, and Logistics Consulting Services (541614), Other Computer Related Services (541519), and Remediation Services (562910), reflecting her expertise in managing technical support, environmental cleanup, and operational logistics for tribal health facilities. She also routinely procures plumbing, heating, and air-conditioning services (238220) to maintain critical infrastructure in remote and underserved locations.
