At 105 years old, Sister Jean Dolores is thrilled about a new season of basketball at Loyola University in Chicago.

Simply known as Sister Jean, she leads the team in a pre-game prayer before matches and takes the first hit as a good luck charm. “she’s like another coach,” one of the players told the Chicago Tribune. “She knows her stuff.”

As chaplain for the men’s team for 30 years, she's known as the “basketball nun” — stealing the show and people’s hearts when the Loyola Ramblers made it to the Final Four at the 2018 NCAA basketball tournament.

"I love every bit of it. … It just makes me very joyful,” Sister Jean tells TODAY.com. “I don’t consider it really working. I just have so much fun. These students are a joy to work with. I learn so much from them, and I know they learn from me.”

The centenarian continues to work at least five days a week, commuting from her apartment to campus via shuttle bus, and offering advice, support and hugs to students in her office. She uses an iPad, a computer and is active on email, but it’s the personal connection with young people that matters most.

She celebrated her 105th birthday with seven parties organized by the university, the students and the assisted living community where she resides. “I feel fine” at 105, Sister Jean says. “I eat well, I sleep well and hopefully I pray well.”

Sister Jean is a member of the Sisters of Charity of the Blessed Virgin Mary. She has spent her life working as a teacher, administrator and principal. She says that waking up wth purpose is one of the great lesons she learned in her hundred years. She’s also coached basketball and other fun sports.
