  • St. Margaret Mary, Pray For Us

    St. Margaret Mary Alacoque had several visions during her lifetime, which became the foundation for the Catholic devotion to the Sacred Heart of Jesus.

Welcome to St. Margaret Mary Alacoque

We’re an intergenerational community of Catholics, committed to living and worshiping in the Sacred Heart of Jesus. 

Visit us soon and we’ll introduce you to some of our friendly parishioners. Here, you’ll find a neighborhood parish, where you can deepen your devotion to Jesus Christ through the Mass and sacraments. You’ll discover the strength of our parish school and faith formation programs, and you’ll find many ways to connect with those who live and work in the area. 

Together, we’re reaching out in love and service to the larger community. We invite you to join us for Mass any day this week. Come, experience life inside the heart of Jesus!
