St. Mary’s intentionally limits its school fundraisers to three 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 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.
