What our Customers are Saying
Mission Work: Revive Liberia
Revive Liberia Missions (RLM) is a not-for-profit organization that is working to restore God's church in the African nation of Liberia. Liberia is an English speaking nation on the western edge of central Africa. It is recovering from many years of civil war which took its toll on the nation's churches.
Our goal is to strengthen the church by assisting our Liberian brothers and sisters as they work to repair their war torn nation. We are working on several different fronts to meet this goal.
Allsteel supports Revive Liberia with funds and manpower.
