One of the many things that makes SIS so special is the way we learn about our Catholic faith and integrate it into everything we do. Our Junior High students especially look forward to visits from Fr. Matthew throughout the month. These meaningful conversations give them the opportunity to talk, ask questions, and grow in their relationship with God. ❤️

Today, we pause to remember and pray for the lives lost and honor the heroes among us. May we never forget the lives forever changed by September 11th and may we continue to honor the courage, sacrifice, and service of those who responded that day.

May God grant eternal rest to those who lost their lives, comfort to their families, and strength and peace to all who continue to carry their memory.
