Maria Rosario M. Arenas

Maria Rosario M. Arenas serves as a Senior Acquisition Specialist at USAID/Thailand, where she leads the end-to-end procurement lifecycle for technical assistance and advisory services critical to the agency’s mission of advancing regional resilience in Southeast Asia. She manages complex acquisitions aligned with USAID’s strategic priorities in public health, climate adaptation, governance, and inclusive development, ensuring compliance with federal acquisition regulations and U.S. foreign assistance policy. Her work directly supports the deployment of expert personnel and capacity-building initiatives through competitive, transparent, and results-driven contracting processes. While no specific contractor relationships are currently identifiable due to data limitations, Ms. Arenas routinely engages with a broad spectrum of professional service providers, including international consulting firms, technical implementers, and local regional partners. Her procurement approach emphasizes merit-based selection, performance-based contracting, and rigorous vendor evaluation to ensure high-quality deliverables in complex, cross-border development environments. Ms. Arenas has a uniform preference for open, non-set-aside competitions, with 100% of her acquisitions conducted without socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB. This reflects a strategic focus on securing the most technically qualified and globally experienced providers to meet USAID/Thailand’s high-stakes development objectives, prioritizing expertise and performance over socioeconomic classification. Her procurement portfolio is overwhelmingly concentrated in NAICS 541990 (All Other Professional, Scientific, and Technical Services), with secondary emphasis on management consulting services under NAICS 541611 and 541618. She specializes in acquiring strategic advisory services, communications strategy development, environmental resilience planning, and public health technical support—domains requiring deep subject-matter expertise and adaptive implementation frameworks tailored to Southeast Asia’s evolving development landscape.
