Joan Purcell was born on September 23, 1941 on the island of Carriacou where she received her primary education. She went on to pursue tertiary education at the University of the West Indies and University of Toronto where she was awarded a Bachelor and Master degree in social work. In 1983, when she was called to political life, her training in social work and her interest in community and participatory development enabled her to take advantage of the opportunity to play an important leadership role. Purcell first served as Deputy Leader of the NDC, and later as political leader, leaving an indelible mark on party members and paving the way for future female leaders in the tri-island state.

Purcell had several stints in government. Her journey began as President of the Senate, a position she held from 2008 to 2013. She also served in both the upper and lower houses, followed by stints as a member of Parliament and Acting Prime Minister.

Although she is retired from frontline politics, Purcell continues to serve her community as a consultant in the areas of leadership and social development.
