Meet the Program Management Office

The NIEM Program Management Office (PMO) executes the vision of NIEM established by the Executive Steering Council (ESC), while managing the day-to-day operations of NIEM. The office encourages the adoption and use of NIEM and oversees all working group and committee activities, regularly coordinating with communities of interest (COIs), principal stakeholders, and other information-sharing initiatives to promote collaboration and interest in NIEM priorities.

NIEM is an interagency program with shared funding and staffing resources; the PMO reflects this.

There is a lot of work that still needs to be done, and I'm excited to have the opportunity to help.” ​​​​​​
