The Sevasadanam School was started in 1989 by Dr. Ganta Vasanthamma, a  leading physician in the town of Madhira. The School’s origins are rooted in Dr. Vasanthamma’s desire to provide quality services for individuals with mental retardation and to combat the stigma that currently exists for this disability.  To that effect, she purchased land in Madhira, constructed a school building, and hired trained staff from the National Institute for Mentally Handicapped (NIMH)  Hyderabad, India.

Sevasadanam School started humbly with a strength of 3 students in a small room. Mr. Ravi and Mr. Raj Shekar, both from NIMH, assisted in the initial years of the School's development before returning back to NIMH to pursue research activities. 

Mr. Salaam, assisted by Mr. Satyanarayana streamlined the administrative and functional activities of Sevasadanam. They improved the activities of the students, increased parents interaction, advocated for the starting of a hostel at Sevasadanam and increased the awareness of the activities of the School to the local population.  Sevasadanam grew gradually over the years and additional buildings were constructed including classrooms and a dining room to accommodate the increased student strength.

Dr. G. Vasanthamma was the driving force behind the successful growth of Sevasadanam.  She had a vision to help the mentally disabled children and adults at the Sevasadanam School, and worked tirelessly to make her vision a reality.
