Home / Glossary / Sister Mary Louise Petro

Sister Mary-Louise Petro is a Sister of Mercy, of the Parramatta Congregation, which she entered in 1973.

Before entry Mary-Louise graduated from the Catholic Teachers’ College and following her religious profession in 1975, taught and was Deputy Principal at both Our Lady of Mercy College (OLMC), Parramatta and Epping.

Our Lady of Mercy College, Parramatta, is a private, Roman Catholic, day school for girls, located in Parramatta.

In 1983, she obtained a qualification in Youth work and led the Mercy Youth Team in the parishes of St Clair and St Marys in Sydney’s West.

From this ministry, local parents requested ways to assist young people who were unemployed in a time of extremely high youth unemployment.

In response Mary-Louise, with the support of the Sisters of Mercy, founded The Mamre Project at St Marys, in 1985. This ministry was a sponsored work of the Parramatta Sisters of Mercy and assisted the unemployed, people with a disability, youth at risk and refugees.

Roles within the Sisters of Mercy have included formation of younger sisters and three terms on the Leadership Team. Mary-Louise is currently the Congregation Leader for her order.

Sister Mary Louise brings with her a wealth of community knowledge and expertise.
