Affected by the 1979 insurgency, Uganda underwent a crisis in the supply of medicines. The Church through its Bureaus Uganda Catholic and Uganda Protestant Medical Bureaus made a key decision to transit from the heavy donor reliance. A decision to form Joint Medical Store, a non-profit organisation was to ensure procurement of quality medicines for the mission based facilities (Private Not for Profit Facilities)

This would facilitate sustainability and empower the facilities easily access quality medicines.

This journey has streamlined the pharmaceutical supply chain enabling the channelling of not only regular supplies but also donor funded items through JMS. During the 38 year journey, JMS has expanded its services to include repair, servicing and maintenance of medical equipment and capacity building. It has also opened up a branch in Mbarara serving Western Uganda.
