A Nigerian consulting firm built on evidence and systems thinking
Evidence, systems and impact for governments, development partners, NGOs and businesses.
Who we are
Impact-Tri & Atlas Consulting Services Limited is a Nigerian multidisciplinary consulting firm providing evidence-driven research, technical assistance, institutional strengthening, programme design, monitoring, evaluation, learning, policy and strategic advisory services.
We work across government, development partners, civil society and private-sector institutions, with particular strength in Water, Sanitation and Hygiene (WASH), health, environment, governance, climate resilience, social inclusion and institutional development.

Health
Public health outcomes, and the community systems that protect them.
Environment
