We are excited for the transformative impacts they will have on our organization, clients, partners, and ultimately, the Navajo Nation.”

Jeff Abney, Vice President, Department of Defense (DoD), has served as a leader within the family of companies for eight years. Following his role as Air Force Portfolio Director, Jeff ascended to President of DDC IT Services (DDC ITS), directing remarkable growth from a $12 million-dollar 8(a) certified company to a thriving firm boasting $60+ million in revenue and a workforce of 200 employees. Under his stewardship, DDC ITS and Red Canyon Technologies (Red Canyon) excelled in delivering 90+ defense contracts in support of mission-critical operations.

Rachel Cross, Vice President, Navy and 4th Estate, brings 16 years of accomplishments with DDC. Commencing her career with NOVA-Diné in quality and configuration management supporting DISA, her client-centric approach led to a four-year tenure as DISA and Army Portfolio Director for DDC ITS. As a result of Rachel’s adept leadership, DDC ITS experienced unprecedented growth in portfolio expansion of 400% from annual revenues of $7 million in 2017 to $37 million in 2021.
