She manages a diverse portfolio of service-based acquisitions including facility maintenance, transportation logistics, and equipment leasing, ensuring compliance with federal regulations and mission-aligned requirements.

Ohi maintains longstanding contracting relationships with key vendors including KOTRACK INCORPORATED, BRANSCOME OPERATING, LLC, MOTOROLA SOLUTIONS, INC., AMD INTERNATIONAL TECHNOLOGIES LLC, and KOTSUKENSETSU CO., LTD., reflecting a mix of domestic and international contractors. She engages primarily with established service providers capable of delivering complex, geographically dispersed support under time-sensitive operational constraints. Her procurement approach emphasizes reliability, regulatory adherence, and performance-based outcomes, fostering stable vendor partnerships that align with long-term mission sustainability goals. Ohi’s contracting portfolio reflects a strong preference for full and open competition, with 100% of awards issued under no set-aside categories. This indicates a strategic focus on maximizing competition among qualified vendors rather than socioeconomic set-asides, prioritizing capability, capacity, and mission readiness over socioeconomic classifications. While small business participation is not formally targeted, her awards remain accessible to all eligible contractors under open solicitation procedures. Her primary procurement focus centers on NAICS 811310 (commercial and industrial machinery repair), NAICS 485510 (charter bus services), NAICS 561730 (landscaping), and NAICS 532111/532490 (passenger car and equipment rental). She specializes in acquiring maintenance, mobility, and facility support services essential to daily base operations, demonstrating deep expertise in logistics-enabled sustainment contracting within a theater-specific, expeditionary environment.
