Shri P.D. Jadhav, popularly known as Annasaheb established Bhartiya Samaj Unnati Mandal in 1948 with a motive of 'A Literate India'. Being aware of lack of education facilities in the rural parts, Annasaheb took up a mission to bring schools within a reachable distance for the large population residing in the darkness of illiteracy and poverty. For this segment of people, education was a distant dream. Annasaheb realized that merely bringing school was not a solution for people without proper food, clothing and shelter. For this reason Annasaheb established 'Ashram Schools', where food, clothing and shelter could be provided with education. He traveled around the Bhiwandi area of Thane and soon established 15 primary and secondary schools and 6 'ashram schools'. After his sad demise, the Organization continued his work, however could not manage to make much progress.
A few years later in 2006, Annasaheb's son, Shri Vijay Jadhav and Shri B. D. Kale One of his close aides took charge and fresh beginning for Padmashri Annasaheb Jadhav Bhartiya Samaj Unnati Mandal, was made. With the efforts of the team under this new leadership, today, about 40,000 children are getting education through 28 primary and secondary schools, 12 'ashram schools' and 8 higher secondary schools and colleges. Schools and 'Ashram Schools' under the aegis of PAJBSUM are spread in 18 villages surrounding Bhiwandi catering mostly to the unfortunate section of our society.
