Today, we celebrated 135 incredible years of Catholic education at our Alumni Prayer Service. Together, we reflected on cherished memories, the blessings of the past, and the many reasons we love St. Mark. A heartfelt thank you to all the alumni who joined us today and to everyone who participated in the service. Take a moment to watch this video and look back on the rich history and legacy of St. Mark School! #stmarkschoolcatonsville #AOBCatholicSchools #CSW2025 #csw25 #alumniprayerservice | St

Happy Counselor Appreciation Week to our very own Mrs. Sites! ✨ Thank you for helping our students grow in confidence, kindness, and resilience — and for walking with them through every step of their journey. Mrs. Sites’ ever impressive way to know exactly what 500 students need on a daily basis is exactly why we consider ourselves so lucky that she is ours! Thank you for the classroom lessons, lunch bunches, group sessions, and PBIS leadership. We are truly blessed to have you! 💙 #CounselorApp
