The convent is located in Avadi, a suburb of Chennai, surrounded by major defence establishments. The people are a mixture of upper, middle and lower economic class of the society. A lot of educational institutions have emerged in and around Avadi. This place is historically significant for the presence and activity of the military during the pre-independence period. 


In 1953, Most Rev. Dr. Louis Mathias, sdb, the then Archbishop of Madras-Mylapore, invited our sisters to establish a convent and to cater to the educational needs of the people of Avadi. Since then, the sisters have been devoted to the teaching ministry at Avadi.

This mission was realised through the support and encouragement of Mother Mary Dominic, the then Superior General. A new convent building was constructed and blessed on 17 November 2012 by

Most Rev. Dr. A M Chinnappa, sdb, the then Archbishop of

Madras-Mylapore, in the presence of Mother Rita Catherine Michael, the Superior General.


The sisters at Avadi tirelessly render their services in the field of education since 1953. Following the invitation of the then Archbishop, Most Rev. Dr. Louis Mathias, sdb, St. Antony’s Middle School was established in 1953 and in 1960, the Immaculate Heart of Mary’s Girls High School was established. In 1964, Lucia’s Home for Children was opened to provide better education for those children who come from distant villages. Then in 1978 The Immaculate Heart of Mary’s Girls School was upgraded as a Higher Secondary School. In 1987, St. Joseph’s Matriculation School was started to provide education to the children of those working in the defence sector. Presently, there are about 7,500 students being educated under the patronage of our sisters in all the three educational institutions. Besides teaching in schools, the sisters also involve in various other ministries such as visiting the settlements of gypsy communities and prison ministry. The sisters also contribute to the pastoral needs

of the parish through various activities, especially in the substations of the parish.
