DMSEDO is a non profit, nonpolitical, voluntary organization committed for a people centered development group and is dedicated to serve the rural poor and the downtrodden people. The development program around Williamnagar area was initiated in 1986 by Church's Auxillary for Social Action (CASA) with the active cooperation of Garo Baptist Convention (GBC). Since then efforts are being made to educate village communities on various socio-economic, ecological and other factors which are not allowing the people in the society, especially the poor and marginalized so they may enjoy sufficient and secure life. The education process prompts the villagers to form different committees like a Village Level Committee, Women Association, Self Help Group etc. to strive for achieving all around development in the area.The District level committee drawing its members from the village key leaders in the area and act as advisory body to different development committee at village level. Through the advisory committee its members felt the needs to have an active development organization in the
