PPI Associates

PPI Associates are individuals who direct, co-direct, or are closely involved with one or more of PPI's programs but who are not members of the Steering Committee.  Like Steering Committee members, Associates have demonstrated a long-term commitment to particular issues and have either worked extensively with PPI in the past or have been involved at the Affiliate level.  Associates allow PPI to broaden and strengthen its scope and impact, providing a sound basis for institutional growth.
