Mamaa was born and raised in Ghana and has lived and worked across four countries including the UK, US and Hong Kong. She is the lead for WPP Roots – WPP’s ethnic & cultural diversity employee network which plays an active role in amplifying the voices of ethnic minority leaders within the company and creating platforms for ethnic minority women to share their experiences. She has actively worked to embed inclusive thinking throughout WPP’s global network – leading Roots’ expansion, and successfully launching a workshop called “Covering in the workplace”, which explores how ethnic minority employees cover aspects of their identities in order to fit in. She also created an Anti-Racism Resource Pack following George Floyd’s death featuring support resources for Black women. As well as providing informal mentoring for junior colleagues at WPP, Mamaa provides mentorship to young female students at Aves International Academy in her hometown of Tema, Ghana.
