Own The Moment (OTM)

When we have the privilege of interacting with a Veteran through our work, we can do much to recognize and value them. The “Own the Moment” initiative within CSP is aimed at helping all CSP staff (and potentially a broader research community) learn ways to better show them that they are the “why” behind what we do.

VA CSP Knowledge, Information Transfer, and Education (KITE) Speaker Series

The KITE speakers series offers conversations with past and present CSP and other VA research leaders who will share their perspectives on a wide range of topics and provide real-life examples of their leadership in action.  By capturing, sharing, and documenting this institutional memory, the Program’s ability to serve as a model for the VA research enterprise will be enhanced, while integrating its activities with VA’s broad network.
