RUMFORD — Holy Savior Catholic School begins its 100th year with two new libraries, two new staff members and lots of plans to celebrate its centenary.

Barbara Pelletier, teaching principal, said 53 Pre-K through eighth-graders are enrolled in the small school for the first day of class Aug. 29. Families still may enroll their children.

The library, that up until this year served all students, is now two libraries – one for grades K-3 and the second for grades 4-8. The libraries also have a new librarian – Ashley Duguay who is three-quarters way through her B.S. Degree in Library and Information Science from the University of Maine at Augusta.

Duguay, a 2009 Mountain Valley High School graduate and a resident of Mexico, has been busy the past few days sorting and shelving the thousands of books for primary- and elementary-age students. She replaces Brenda Sassi who has retired. Besides working at Holy Savior, Duguay also works part-time at the Mexico Public Library and is taking courses in the Rite of Christian Initiation for adults to become Catholic.

The library was cleaned, painted and rearranged by a missionary group known as Beyond Sunday Missions from Massachusetts this summer.

Also new this year is Kim Clark of Mexico. She is a 2007 graduate of Mountain Valley High School with an elementary teaching degree from the University of Maine. She replaces Sonia Thibodeau as a pre-K assistant teacher. This is Clark’s first teaching position.

The school and supporting Parish of the Holy Savior Church also will welcome a new pastor in November. The Rev. Robert Vaillancourt, who had previously served as director of religious vocations in Portland, replaces The Rev. Phil Tracy who has been reassigned to Sanford.

The 100th anniversary of Holy Savior Catholic School, originally known as St. John’s Catholic School, will be celebrated Sept. 8 with an open house, book fair, and memorabilia displays from 2 to 3:45 p.m., followed by a celebratory mass at the church at 4 p.m. After services, a social hour will take place in the basement of the school.

Pelletier, who is beginning her 41st year with the school, said lanterns and candles during the mass will list the principals and pastors who have served the school since 1912.

Several sisters who had taught or served as principals of the school also are expected to attend.

Pelletier said a variety of other events are being planned to mark the school’s centenary.
