Kalvialaya
Kalvialaya is a NGO registered in 2010, an initiative by M Selvakumar, an alumnus of PSBB school, to help the rural and disadvantaged children of India get education, coaching and guidance. The program helps young people learn to communicate, to build self-esteem, and to make healthy decisions for their futures. It also teaches professional skills to give them greater opportunities for employment, thus lowering their likelihood of future delinquency. The organisation works for the benefit of poor communities of villages in and around Pilapur near Chengelpattu, Kanchipuram District, Madhuranthakam Taluk to combat the continuous adoption of child labour, low daily wages, domestic and community violence, and high levels of unemployment.
