Theresa Maranto Foster

Theresa Maranto Foster, age 76, of Baton Rouge, Louisiana, passed away peacefully on Tuesday, February 24, 2026, surrounded by her family, after bravely fighting Alzheimer’s and Parkinson’s for many years.

Theresa was cherished for her gentle, loving, and compassionate nature throughout her life. She graduated from Baton Rouge High School and devoted herself to serving others, both through her work and her faith.

For over two decades, Theresa was a pillar of the Our Lady of Mercy community. She first served as the assistant bookkeeper and office assistant at Our Lady of Mercy Catholic School and later became the receptionist and funeral coordinator at Our Lady of Mercy Catholic Church, making a lasting impact on countless individuals until her retirement. In addition to her ministry work, Theresa joyfully served as a member of the church choir, was a dedicated member of St. Matthew’s Guild, and offered her time as a Eucharistic minister to the homebound. Her deep commitment to her family matched her dedication to her service, providing unwavering love and support.

Theresa was preceded in death by her beloved husband, Charles “Snow” Foster, Sr.; her parents, Joseph and Antionette Maranto; her sister, Diana Maranto Gauthier; and numerous aunts, uncles, and cousins.

She is survived by her children, Charles “Chuck” Foster, Jr. (Laura) and Dawn Dicharry (Dale); her siblings, Toni Roumain, Cecile Johnson, Mary DeVilleneuve (Jon), Bernadette Sampere, and Joe Maranto (Connie); brother-in-law Roy Foster (Phyllis); as well as many nieces, nephews, and cousins who will deeply miss her.

Visitation will be held from 9:00-10:00 a.m. on Monday, March 2, 2026, at Our Lady of Mercy Catholic Church, 445 Marquette Avenue, Baton Rouge, LA. Mass of Christian Burial will follow at 10:00 a.m. Burial will take place at Resthaven Gardens of Memory, 11817 Jefferson Highway, Baton Rouge, LA.
