Prof. Peace Mamle Yoko Tetteh

Professor Peace Mamle Yoko Tetteh is a Ghanaian academic and chemist whose expertise in chemistry and chemical engineering informs her governance role at GOIL Ghana, the country's largest oil marketing company. Her professorial appointment reflects a career built in academic science, and her presence on the GOIL board brings a technically grounded perspective to the governance of a company whose operations are fundamentally rooted in the chemistry of petroleum products and their safe handling, storage, and distribution.

GOIL Ghana operates one of the most extensive fuel retail networks in the country, distributing petrol, diesel, liquefied petroleum gas, and lubricants to consumers across Ghana's urban and rural markets. The technical dimensions of these operations, including product quality assurance, safety standards for storage and handling, and the environmental management of petroleum infrastructure, benefit from board-level oversight that includes scientific expertise alongside the financial and commercial perspectives more typically represented in corporate boardrooms.

Her academic background in chemistry places her within a tradition of Ghanaian science that has produced significant contributions to research and education, particularly at the University of Ghana and other leading institutions. Scientists who bring their expertise into corporate governance contribute a form of board diversity that goes beyond gender: the diversity of professional formation that helps boards engage with technical risks, environmental responsibilities, and science-based decision-making that purely business-trained boards may find more difficult to navigate effectively.

Her recognition in the 2026 Avance Media Top 100 Women Board Directors ranking, which examined board compositions across 100 of Ghana's leading public and private institutions, confirms her standing among Ghana's significant women in corporate governance. Her board role at GOIL represents the application of scientific expertise to the oversight of a major commercial enterprise, a combination that enriches the governance of an institution whose technical operations require exactly that kind of informed oversight.

Her work at GOIL Ghana connects her to the governance of a company that is central to Ghana's petroleum downstream sector and whose operations span the country's most important fuel distribution infrastructure.
