Being an ardent devotee of Sri Ramakrishna Paramahamsa, all the institutions started by the Trust bear the name of the HolySage "Sri Ramakrishna".
Following the Principles of Sri Ramakrishna Paramahamsa's Philosophy of God through man', the Trust successfully runs 14 organisations significantly catering to social causes of society focusing on Health Care, Education and Service. Apart from healthcare, it is education that has attracted the attention of the SNR Sons Charitable Trust. This extraordinary penchant for education has resulted in bringing some of the sterling Educational Institutions and Courses within the reach of many, who would otherwise have been left dreaming about education at such levels.
