Lois A. Pentecost was born February 13, 1932, in Lewistown, Montana, to Claude and Ida Ellen
(Crowley) Pentecost. As the youngest child, she appreciated her siblings, Jack, Dorothy,
Genevieve, Tom, Marjorie, Tim, Rita, Chuck, Jim, and Bette. She entered the Congregation of
the Humility of Mary in 1954 and professed vows in 1957 as Sister Mary Claudellen.
Sister studied education both at Ottumwa Heights College in Ottumwa, IA, and at Marycrest
College in Davenport, where she earned her BA in Elementary Education.
Sister Claudellen began teaching in 1957 at St. Anthony Elementary School in Des Moines.
Then she served one year, 1960-61, at St. Mary’s in Centerville, IA, before leaving Iowa,
spending over 20 years at different schools in Montana, including Sacred Heart School in
Glendive, St. Joseph, St. Mary, and St. Gerard in Great Falls, and St. Leo in Lewistown where
she also served as principal. She taught one year at St. Austin in Minneapolis. Other positions
included school bus driving and serving as supervisor of the wood shop and sewing areas at the
Easter Seal Adult Center in Great Falls. In 1983, she returned to Iowa and served as Center
Coordinator at the Humility of Mary Center in Davenport until 1987. She returned once more to
Great Falls to work as a bus driver and then for Columbus Hospital—Benefis West as a central
services technician. In 2015, she retired at the Humility of Mary Center where she served in the
ministry of prayer and witness.
A self-described tomboy, Sister is remembered for her love of sports (particularly softball and
boxing), playing the guitar, hunting, fireworks, and making jelly and wine from chokecherries
she gathered by the bushel. In Davenport, she was part of a group that would work through the
night on Christmas Eve, decorating the Center to exacting and delightful standards. Her
enthusiasm and laughter will be dearly missed by all who knew her.
She is preceded in death by her parents and all ten of her siblings, but is survived by many
cousins, nieces, nephews and members of her religious community.
Memorials may be made to the Congregation of the Humility of Mary.
