Since November 2006, Arkangelo Ali Association (AAA) has been providing health services to the destitute populations of Southern Sudan. Its roots go back to the health department of the Diocese of Rumbek, where AAA founders (Mrs. Natalina Sala & Dr. Callixte Minani) had been working since 1997.

The decision of transforming the health department of Diocese of Rumbek into an independent NGO was prompted by the new period of peace opened after the Peace Agreement between the Government of Sudan and the Sudan Peoples' Liberation Army/Movement (SPLA/M), signed on 9th January 2005. In this crucial moment, AAA wanted to expand its health services to new areas after it had been requested so by the Ministry of Health depending from the Government of South Sudan (GoSS).

"At this moment AAA operates in six of ten states of Southern Sudan, namely Lakes, Northern of Bahr-el Ghazal, Warrap, Western Bahr -el Ghazal, Western Equatoria and Central Equatoria. It employs 300 Sudanese Nationals and 40 expatriate staff (doctors, nurses, laboratory technicians and logisticians). During all these years, AAA has made a deliberate effort to form and train local staff as a main means of building and strengthening local capacities. This is a titanic effort in a context where education levels are still very low after long years of armed conflict and displacement.
Also AAA has improved its representation in the field by means of a liaison office in Juba and a support office in Rumbek. Due to the logistical constraints concerning the access to South Sudan, AAA has also a regional office in Nairobi, under the auspices of the Verona Fathers (Comboni Missionaries, Kenya Province).

AAA is a member of Bakhita Consortium, a group founded in 2005 of eight Italian, Kenyan and Sudanese agencies working for the development of Sudan and its peoples with the purpose of fostering an more effective cooperation and collaboration in the implementation of humanitarian and development work in the Sudan.
