Mayo serves as a Contract Specialist at the Defense Finance and Accounting Service (DFAS), where he plays a pivotal role in executing acquisition strategies that support the agency’s mission of fiscal accountability and financial system modernization. He manages a diverse portfolio of procurement actions, primarily focused on professional services, facility support, and administrative infrastructure contracts. His work ensures compliance with Federal Acquisition Regulation (FAR) standards while advancing DFAS’s objectives in audit readiness, automated reporting, and secure financial operations.

His primary contractor relationships include Soderberg Company Inc., Ecology Mir Group LLC, Bloomberg Industry Group, Inc., and Roche Diagnostics Corporation, reflecting a mix of specialized professional services, facility management, and technical support vendors.
