The Diffun Saranay Development Cooperative (DISADECO) was born on July 2, 1988 when 51 poor rice farmers from the four barangays of Ma. Clara, San Isidro, Isidro Paredes and Bannawag met under the shade of a mango tree at the Gabrillo Residence at Ma. Clara, Diffun, Quirino to discuss ways and means to improve their lot. Resultantly, the group decided to organize a cooperative calling it the Diffun Credit Cooperative Inc. (DCCI). Subsequently, trainors from Santiago Credit and Development Cooperative (SACDECO) with the assistance of MAO Romulo Mandac of the Department of Agriculture conducted a pre-membership seminar. Likewise, the first set of officers was elected as follows:
           Ramon B. Piano – Chairman
           Corazon T. Ballesteros – Vice- Chairman
           Benjamin B. Gabrillo – Treasurer
           Elizabeth G. Somera – Director
           Rogelio P. Dela Cruz – Director
           Pablo T. Sado – Director
           Marcelo O. Arcebal – Director
It started its operations with FIVE THOUSAND TWO HUNDRED (P5, 200.00) paid-up share capital.A non-government organization, the World Vision International, whose mission is community development invested P40, 000.00 to the cooperative and also helped out in registering it with the BACOD.
Only a few months after its registration with BACOD, key officers (chairman, vice-chairman and manager) resigned due to transfer of employment. The budding cooperative suffered its first test. The remaining officers were unfazed, however, a reorganization immediately took place. Rogelio Dela Cruz was elected chairman, Elizabeth G. Somera as Vice-chairman, Benjamin Gabrillo treasurer, Fausta Garcia Secretary and Pablo Sado and Evaristo Acebo as members of the BOD. The officers sweated a lot in educating would be members for people are sick of the “Kita-Pati” syndrome. Sacrifices paid off for after six years of operations. Membership grew dramatically convincing the general membership to amend its constitution and by-laws. In March 21, 1994, the area of operation was amended from municipal-wide to province-wide and name was amended as Diffun Credit and Development Cooperative (DICREDECO).
