Tumelong Mission provides a safe, loving, caring environment for orphans and vulnerable children affected by the AIDS epidemic.

The Thusong Hospice, where at least one of the parents has been a patient, has referred majority of the children in the mission to them. The community strongly supports Tumelong Mission, believing that the orphaned children must not be institutionalized but remain in the area so that they will not lose their customs or language. Without placing increased pressure on next of kin and/or guardians, Tumelong Mission assists in providing schooling, transportation, meals and healthcare, to ease the increased responsibility on the families and the community.

Oprah's Angel Network provided a grant to Tumelong Mission to support their general operating costs.
