From Our Clients:

“As the Chair of Nuestros Pequeños Hermanos International (NPHI), an organization serving children and youth in situations of vulnerability in Latin America and the Caribbean, I have worked closely with SESIL PIR Consulting GmbH in preparation of our Board Meetings, which Sesil also facilitated. In addition, Sesil has served as a consultant on HR matters for NPHI.

Working with Sesil has been an outstanding experience. Due to Sesil’s organizational skills, insights and creative problem solving NPHI has made great progress in our strategic planning process and our board work in general.

Sesil facilitated our board meetings in a thoughtful and constructive matter, moving us forward in our discussion of the many topics and tasks we have to accomplish.
If you are in need of a consultant for Human Resource issues, strategic planning, or meeting facilitation, I strongly recommend Sesil Pir. She is a person of integrity that will produce results for you and your organization.
