Boureima and Susanna lead Fulani Ministries whose vision is to spread the Gospel amongst the Fulani people. Living in 19 African countries, they are one of the largest unreached people groups in the world. Much of the work is centred at the Jam Tan training school in Burkina Faso, which trains Fulani Christians in discipleship and church planting, as well as serving the local community providing education, regular health days, poverty relief and teaching practical skills such as weaving and tailoring.
Boureima and Susanna Diallo live near Ouagadougou with their 3 children. Boureima is originally from Burkina Faso, but became a believer while studying in the UK, where he also met Susanna. Shortly after their first child was born, they moved back to Burkina Faso to work among the Fulani people.
