Chisomo was started as a program of Full Proof Mission, by Rev. Aaron Chilunjika in 1991.
Chisomo Drop in Centre opened its doors in October 2002. It was first located at the Zambia Printing Company plot 2348 Kabelenga road, light industrial area, Lusaka Zambia. The building was used for only a year and half and then was asked to vacate the premises.
It has been in its present location at 32 Makishi Road, Northmead, Lusaka, Zambia since 2003. Chisomo has become the hub of Full Proof Mission where all programs relating to children in need are administered.
