Who we are

Pushing boundaries

Diabetes Africa is a non-profit organisation founded by a young British-Nigerian pharmacist whose family has been affected by diabetes and its complications.

Our journey began by identifying and connecting  healthcare professionals from across the continent and the diaspora. Our network now extends to entrepreneurs, financiers, and decision-makers, looking for new ways to alleviate the burden of the disease.

Pushing Boundaries with Diabetes Africa


To accomplish our work, we are supported by members, organisations championing initiatives, partners and donors.

Our work programme is reviewed by a Council of Advisers comprising sector specialists from Africa and the rest of the world. Its business function is overseen by external non-profit and management experts.
