  • Synthesize and disseminate key discussion points, decisions, and action items from high-level engagements, ensuring clarity and accountability.
  • Proactively manage and deconflict organizational calendars across DASA DE&C and with external stakeholders, anticipating and resolving potential scheduling conflicts to protect senior leader availability for critical engagements.
  • Serve as a key integration point for the directorate, expertly managing senior-level correspondence and coordinating high-level visitor access and support.
  • Task & Knowledge Management
  • Manage the end-to-end lifecycle of all directorate taskers using the Army Enterprise Task Management Software Solution (ETMS2), analyzing trends in tasker performance to recommend process improvements.
  • Synthesize inputs from across the directorate to produce executive-level reports, such as Weekly Activity Reports (WARs), providing nuanced status updates to leadership.
  • Oversee the directorate's knowledge management program, governing information repositories (e.g., SharePoint, shared drives) to ensure compliance with information management policies and intuitive accessibility for the team.
  • Executive Administrative & Logistical Management
  • Manage all aspects of executive travel using the Defense Travel System (DTS), independently handling complex authorizations and vouchers.
  • Develop and produce comprehensive trip books and executive read-ahead materials for senior leader travel and key engagements.
