Trinity President Dr. Rob Mullen said of Brother Charles: “He taught math and physics, coached soccer and track, and carried himself in a kind and caring manner. He had a beautiful singing voice, loved his Irish heritage and was appreciated by his students.

“We coached soccer together for six years. He taught me a lot and remained a mentor. We talked recently during the Christmas break. He was proud of the work we were doing.

“Thank you, Brother, for impacting your students and colleagues in such significant ways.

“May his soul and the souls of all the faithful departed, through the Mercy of God, rest in peace.”
