"There was a need, I had the means, so I wanted to help out," Sister Margaret Ann told CNN.
Sister Margaret Ann said she knew of a chainsaw in her school's closet and felt it was her duty to help remove the tree that was blocking the road.
"We teach our students: Do what you can to help other people, don't think of yourselves," she said during a live interview on CNN. "That's what I wanted to do."
Sister Margaret Ann's school was damaged during Hurricane Irma. A wall was blown in and multiple trees were downed across the property. She said she did not know when they would be able to open the school back up.
"The community will come out and help us. That's what we do," she said. "It's good."
