These experiences give her a 360-degree view of the non-profit and donor landscape, and an intimate understanding of the challenges faced by those who lead within it.

Her consulting practice focuses on strategy development and facilitation, organisational design, and leadership development, working with non-profits, philanthropic foundations, sector associations, and multi-stakeholder collaborations. 

As a Leadership Coach, Sibongile works with senior leaders and executives, both one-on-one and in groups, supporting them to lead beyond authority, build sustainable careers and grow into their fullest potential.
