The purpose of St. Mary’s School is to provide opportunities for the child to develop his/her potential: spiritually, intellectually, socially, and emotionally, in a secure, caring and stimulating environment.

St. Mary’s is committed to teach the Gospel message of Christ; to build a community characterized by sharing, teaching, and believing; and to serve through prayer, worship, and social action.

We believe each child is a unique individual with skills and talents that must be cultivated and needs that must be recognized and met. We are dedicated to excellence in education and to fostering an atmosphere of self-learning, critical thinking, responsible action, and peacemaking.

The school’s focus on religious education, high academic standards, and the celebration of spiritual and community values nurtures the development of a positive and productive approach to successfully meet the challenges of modern life.

“The spiritual integrity and conscience, that these days is often hard to establish in our youth, are embedded in the way they are taught and guided at Saint Mary’s.”

– Silvana Bruno –


St. Mary’s School nurtures and educates young children and develops a strong academic, faith-filled foundation for our students to become compassionate, responsible Catholic citizens.

St. Mary’s School:

  • Provides a safe, nurturing environment for every student to excel
  • Recognizes and intellectually challenges every student
  • Fosters critical thinking
  • Celebrates spiritual and community values
  • Develops and calls well-prepared Catholic citizens to leadership and social action
  • Empowers life-long learners to participate in an ever-changing world



Children participate in daily religious classes where Christian values are emphasized and the teachings and traditions of the Catholic Church are studied. Students attend Mass one day a month, on holy days of obligation and other special occasions.

Research shows that Catholic schools:

  • Foster a Catholic identity and values
  • Provide a safe, disciplined environment
  • Support a climate where it is important to study and excel
  • Motivate students to learn
  • Encourage parents to participate in their child’s education
  • Promote moral development
  • Honor religious and cultural traditions
  • Foster a lifelong commitment to community service and respect for others
  • Experience fewer drug and alcohol problems

“A child’s first experience at school can put into motion a lifelong love of learning. Both my daughters attend St. Mary’s and are thriving there. The teaching staff genuinely cares about the students and have set the standards high. The environment is friendly and the entire student body interacts with one another in such a positive way. Being a working mom I’m very particular about my children’s care and daytime experience while I’m not with them. At St. Mary’s, I have the great assurance that they are learning, having fun, and truly being cared for. It’s the best decision I’ve made for them and for me.”

Welcome to Saint Mary’s School, Winchester. Our school serves children from pre-school through the fifth grade. We have been educating children since 1914 and are recognized and celebrated for our deep roots and innovative learning. We combine a rich heritage with a state of the art, diverse education.  We have had dedicated religious women, laity and clergy over the years helping to make St. Mary’s School such an important part of the parish and community.  Parents enroll their children not only for the educational/intellectual enrichment but also for the spiritual faith-filled atmosphere in our school community. St. Mary’s is also a fun place to learn!

Our school’s long history and tradition in the Catholic Church provides a solid foundation upon which parents, faculty and staff develop strong values, academic excellence and the tools to meet the challenges of modern culture and life. Please prayerfully consider enrolling your children at St. Mary’s. Our principal would love to hear from you to provide further information and to arrange a tour. You are the first teachers of your children.  It would be our honor to partner with you in the education of your children.

Dear Prosepective Families,


Thank you for your interest in St. Mary’s School of Winchester.   We are so happy to have you here.  St. Mary’s School opened its doors over 105 years ago to serve the educational needs of the Catholic community of Winchester.  Today, our school educates students from over 17 different communities.  We celebrate diversity and welcome students from many cultures and religions.  St. Mary’s School is where education, faith, and acceptance empower our young minds to be leaders fro tomorrow.  Our curriculum focuses on the STREAM model for education; Science, Technology, Reading, Engineering, Arts, and Mathematics.

Our vision is expressed in a commitment to peace and justice, respect for all life, appreciation for the unique gifts of every person, and outreach to those in need. Our parish family affirms all members in their search for truth as they meet the challenge of being Catholics in this modern world.
