Mabel Agyemang has had an illustrious career in the judiciary within three Commonwealth jurisdictions working as a superior court judge. Mabel Agyemang received her undergraduate degree at the University of Ghana and attended the Ghana School of Law. Immediately following her graduation, Agyemang was called to the Ghanaian bar in 1987. She entered private legal practice from 1987 to 1991 before joining the judiciary of Ghana, where she worked in the judicial circuit and served in many different jurisdictions during her tenure.

In 1996, Agyemang became the Vice President of the Association of Magistrates and Judges of Ghana, which she continued to serve in until 2000. It was in 2002 that Agyemang was elevated to the High Court in Ghana. She left her position in the Ghanaian court system to work for the Commonwealth Secretariat. The Commonwealth Secretariat is an association of 54 different countries originally rooted in the British Empire. Its mission is to support mission countries to enable collaboration for global challenges including, those of civil and criminal justice reform. It is in this area of the Commonwealth that Agyemang worked as an expert to the judiciaries of The Gambia and Swaziland as a High Court Judge from 2004 until 2014.

In 2013, Agyemang was appointed to become the first woman Chief Justice of The Gambia, though she was only able to fill the position for a year until 2014. In 2014, she left The Gambia after the President of The Gambia unlawfully terminated her services because Agyemang was attempting to reform the judicial system. She returned to her native Ghana after this removal and was sworn in as a Justice of the Court of Appeals until 2020.

In April 2020, she was appointed by the Governor of the Turks and Caicos Islands to become the Chief Justice of the Turks of Caicos Islands, a position to which she is bringing her years of experience in the judicial field.
