Students attend courses in the STEM Lab (4-8th grades) or Makerspace (K-3rd grades), Art, and PE twice a week. Students can choose to participate in our Strings Orchestra, Wednesday Morning Choir, and Altar Serving at Wednesday Masses, all during regular school hours. Middle School Students choose between various elective courses, including Latin, Home Economics, Architecture & Guitar Lessons.

Many students participate in a variety of SMS sport teams, including volleyball, basketball, archery, cross country and futsal. SMS competes in the Dallas Parochial League and National Archery in the Schools Program (NASP). #GoTigers!

St. Mary’s intentionally limits its school fundraisers to four annual events each year, which are as much community building as they are fundraising. These events include North Texas Giving Day in September, the Run Run Rudolph 5K in December, Annual Casino Night (date varies), and a Clay Skeet Shoot in April.

St. Mary’s students are proud to be Tigers, and our mascot, Toby, periodically makes appearances at various school events!  What is a St. Mary’s Tiger?

All parents are invited to join our version of PTO/PTA, called HASA (Home and School Association). HASA helps build community amongst parents, increase awareness of school opportunities and events, and support our teachers in their efforts to raise our students into becoming saints. Learn more about HASA and its mission here.

Parents are also often seen sharing their time and talents on campus in a wide variety of capacities, including the front office, library, special events, and handyman projects. All adults must be Safe Environment cleared before helping on campus.
