St.Ann's believes in and imparts Sustainable Education and strives to develop a Educational Culture in which students are in sync with social and ecological environment. True to our core value the institution celebrated "Haritha Haram" on 13th August 2019. A tree planting drive was organised under the keen initiative of our Principal, Sr.Emmy Gracy. Staff and students enthusiastically participated by planting trees, thus showing their love and care for Mother Earth.
