AMM Arunachalam Trust, established in 1966, is a charitable organization dedicated to promoting education, healthcare, social welfare, and cultural development. The Trust supports underprivileged individuals, including poor families, orphans, widows, and deserving students through financial and educational assistance, while also providing medical aid to the sick and elderly. In 1981, the Trust acquired and transformed a school in Thiruvattar into a modern educational institution, now serving over 1,600 students, primarily from economically weaker sections, with a strong reputation for academic excellence and outstanding results in Tamil Nadu.
