The Seton HASA supports the school through a variety of fundraising and social activities that are held throughout the year. All parents are welcome and encouraged to join the group. Meetings are held three times a year. Some activities which HASA sponsors include Trunk or Treat, Santa Shop, Santa Stroll, restaurant nights, Father/Daughter dance, Mother/Son Game night, movie nights and other special events. HASA is an integral part of the school community and volunteers always are needed to assist with planning and implementing events.
