Jennifer M Mack

Jennifer Mack serves as a Contract Specialist at Washington Headquarters Services (WHS), supporting the Department of Defense’s mission to modernize institutional management systems and sustain critical defense infrastructure. In this role, she manages the full lifecycle of procurement actions—from market research and solicitation development to contract award and administration—ensuring compliance with FAR and DFARS regulations. Her acquisitions primarily support facility modernization, engineering services, and administrative consulting, enabling efficient enterprise-wide operations across DoD components. She plays a pivotal role in aligning contracting strategies with WHS’s digital transformation and resource optimization goals. Jennifer maintains consistent working relationships with a select group of experienced contractors, including CLARITY INNOVATIONS LLC, CYNERGY PROFESSIONAL SYSTEMS LLC, SIGNATURE RENOVATIONS LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, and GUIDEHOUSE INC. These partnerships reflect a preference for established vendors with proven capabilities in construction, technical consulting, and facility services. Her contracting approach emphasizes performance-based outcomes, clear statement of work development, and rigorous contractor performance monitoring to ensure mission readiness and operational continuity. While the majority of her acquisitions are conducted as unrestricted procurements (71.4%), Jennifer demonstrates a strong commitment to small business participation, with nearly one-third of her awards structured as Total Small Business Set-Asides under FAR 19.5. She actively promotes equitable access for small businesses without favoring specific socioeconomic categories, focusing instead on capability alignment and competitive fairness. Her procurement focus centers on NAICS 236220 (Commercial and Institutional Building Construction), with significant activity in plumbing, heating, and air-conditioning contracting (238220), engineering services (541330), administrative management consulting (541611), and other computer-related services (541519). This reflects her expertise in acquiring integrated facility services and technical advisory support essential to sustaining DoD administrative operations.
