Sheila Johnson-Montalvan

Sheila Johnson-Montalvan serves as a key procurement lead within the IBC Acquisition Services Directorate (140D04) of the Department of the Interior’s Departmental Offices, where she manages specialized acquisitions to support land management, resource stewardship, and infrastructure integrity. Her portfolio centers on professional and technical services critical to federal landholdings, including real estate valuation, aviation logistics, scientific research support, and systems design. She exercises full contracting authority under FAR Part 13 and Part 15, ensuring compliance with federal acquisition regulations while aligning procurements with the agency’s strategic mission to sustain public trust assets through expert, mission-critical services. Sheila maintains enduring relationships with a select group of specialized contractors, including Phoenix Air Group, Inc., Papillon Airways Inc., Brainerd Helicopters, Inc., HMC Helicopter Service LLC, and Mathematica Inc. These partnerships reflect a preference for niche vendors capable of delivering high-reliability aviation, analytical, and technical services in remote and sensitive environments. Her contracting approach emphasizes performance-based outcomes, long-term vendor collaboration, and rigorous source selection under competitive and sole-source authorities as appropriate. A strong advocate for socioeconomic inclusion, Sheila consistently prioritizes small business participation, with over 65% of her awards designated as total small business set-asides under FAR 19.5. She also actively utilizes the Indian Small Business Economic Enterprise (ISBEE) set-aside program, reflecting the Department of the Interior’s unique mission to engage Native communities. Her contracting patterns demonstrate a deliberate commitment to expanding opportunity among small, disadvantaged, and tribally owned firms. Her primary procurement focus lies in NAICS 561110 (Office Administrative Services), 561730 (Landscaping Services), 561720 (Janitorial Services), 611430 (Professional and Management Development Training), and 531320 (Offices of Real Estate Appraisers).
