Director's Leadership Principles

Team Oriented

This agency is large, complex, diverse, and dispersed, but we must still aspire to be a single cohesive team. We will emphasize transparency and open lines of communication as the foundation of teamwork. Historical stovepipes must be replaced with agency-wide integration and we must enhance our ability to anticipate customer needs during crisis, synchronize our considerable resources to increase effectiveness, and work with key partners where our purposes align. It is only through teamwork that the Agency’s strategic priorities can be realized.


People Centric

People are our most valuable resource. DTRA possesses extensive capabilities designed to tackle a wide range of WMD challenges, but these are nothing without the human capital required to develop and implement them. The agency must maximize the strategic impact of its human capital through innovative partnerships and provide pathways for career growth. We must embrace an environment in which all people are valued, and diversity of thought, perspective, background, and identity are embraced and encouraged.


Mission Focused

DTRA’s CWMD mission is both complex and dynamic—one that spans the continuum from adversary threat conceptualization to U.S. forces’ attack mitigation and recovery. However, every member of our DTRA team is united in purpose that our work matters—to our national security, to the well-being of Allies and partners around the world, and to the safety and security of family and loved ones here at home.
