Our Parish also offers two religious education programs:

Catechesis of the Good Shepherd
Parish School of Religion.

The Good Shepherd Preschool

Ages 3 – 5 years

The Good Shepherd Preschool provides a foundation for quality Catholic education through prayer, song and play for our youngest students. We are committed to encouraging spiritual, physical, academic and emotional development of each individual child through discovery-based hands on learning.

As a regional Catholic school, The Good Shepherd program provides the opportunity to bring children and families together as they learn and celebrate our faith. Enrichment programs enhance children’s experience at school by allowing them to explore learning with cooking, art and music.

St. Clare Catholic School

Kindergarten – 8th

Over the 143 years of the school’s operation, we have educated over 3,000 students who have gone into the world and made not just a good living, but a positive change to the world around them.

At St. Clare Catholic School, you will find countless traditions and a sense of community among the families that share common morals and values.  St. Clare provides an environment that values excellence in spirituality, leadership, and service.

St. Clare currently has over 490 students including our renowned preschool program.  This makes us one of the largest Catholic Kindergarten – 8th grade schools in the area.

In line with our mission, our hope for each child is that through the value of incorporating faith formation into all aspects of their education, we are not only building smart students, but we are building strong Catholics who will lead the way in our faith as they grow.

St. Clare students rank among top students in the nation.

Embrace the arts with music, choral, band and art programs.

Amazing preschool program for ages three – pre-K.

Up-to-date technology in each classroom.

Spanish after-school program for grades 5th – 8th.

Over 20 different extracurricular activities.


Religious education based on the teaching principles of Maria Montessori, designed for children ages 3 – 12 years old.

Catechesis of the Good Shepherd (CGS) came about through the work of two Roman Catholic laywomen in Rome: Sofia Cavalletti and Gianna Gobbi. They were inspired by the educational principles of Maria Montessori, also a devout Catholic, who believed that her “method” was fulfilled in teaching religious education. The materials that are prepared for the children, in a special space called the Atrium, are based on the Bible and liturgy. CGS Sessions are held on Sunday mornings and Wednesday afternoons in the Saint Nicholas Spirituality Center.

Contact Martie Rheaume at to learn more about upcoming sessions.

School of Religion

PSR offers religious instruction consistent with the wisdom and tradition of the Catholic Church. Our catechists are people of faith who volunteer their time and talent. They prepare lessons with care and use a curriculum approved by the Diocese of Belleville. By working together with families in a spirit of love and concern for the needs of the children, we hope to create a positive experience of church in the process of passing on the faith.

PSR meets on Sunday mornings
at 9am at Saint Clare School.
