Stephanie McCullough

Stephanie McCullough serves as a primary contracting professional within the IBC Acquisition Services Directorate (140D04), supporting the Department of the Interior’s mission to sustain federal land management and public trust assets through specialized technical and professional services. She manages a diverse portfolio of acquisitions focused on real estate valuation, aviation logistics, scientific research support, and systems design, ensuring mission-critical capabilities are delivered in alignment with federal procurement regulations. Her role is central to securing expert contractors who enable infrastructure integrity and resource stewardship across federal landholdings. McCullough maintains sustained working relationships with key contractors including Phoenix Air Group, Inc., Papillon Airways Inc., Brainerd Helicopters, Inc., HMC Helicopter Service LLC, and Mathematica Inc. These partnerships reflect a reliance on niche providers offering specialized aviation services, data analytics, and technical consulting essential to field operations and land management decision-making. Her contracting patterns emphasize long-term, performance-based engagements with vendors possessing deep domain expertise rather than broad-spectrum service providers. Her procurement approach prioritizes open competition, with 84.6% of awards issued under no set-aside authority. Nevertheless, she consistently supports small business participation, allocating 12.8% of awards to total small business set-asides and 2.6% to Indian Small Business Economic Enterprise (ISBEE) set-asides, reflecting the Department of the Interior’s unique socioeconomic priorities for tribal economic development. Her primary NAICS focus areas include Administrative Management Consulting (541611), Computer Systems Design Services (541512), and Commercial and Industrial Machinery Repair (811310), underscoring her expertise in procuring technical advisory services, digital systems integration, and maintenance support for specialized equipment. She frequently acquires services that bridge operational logistics with data-driven decision-making, reinforcing the agency’s commitment to modernizing land management through expert technical partnerships.
