Mason William Stringer, age 7, of Swansea, passed away unexpectedly on Tuesday, December 30, 2025, at Hasbro Children’s Hospital, surrounded by his loving family, due to complications from undetected acute lymphoblastic leukemia.
Born in Swansea, Mason was the beloved son of Jonathan P. and Sheridan A. (Denert) Stringer and the cherished little brother of Cameron Stringer. Mason brought joy, laughter, and love into the lives of everyone who knew him. His vibrant spirit is evident in his favorite color, yellow.
A second-grade student at Gardner Elementary School in Swansea, Mason was an energetic and enthusiastic child who delighted in staying active. He enjoyed playing baseball, soccer, and basketball, as well as weekly swim lessons. His vivid imagination was evident in building with Legos and Magna-Tiles, playing with dinosaurs and Hot Wheels, creating worlds in Minecraft with his brother, drawing pictures, and writing stories. He especially loved his “stuffies”, board games, the beach, dogs, trampoline parks, arcade claw machines, dancing and music, watching Big City Greens and movies, cheeseburgers, outings to Chili’s and the Ice Cream Barn, picking dandelions for his mother, playing outside with his brother and friends, exploring insects and birds, and enjoying bedtime tickles and stories. Mason treasured vacations in Onset with his cousins, trips to Lake George, North Conway, Atlantic City, and Sesame Place with his family, and most memorably, his first visit to Disney World last year.
Along with his parents and brother, Mason is survived by his maternal grandparents, William and Donna Denert, and his paternal grandmother, Marie Stringer; his aunt Chelsea Robinson, her husband Brian, and their daughter June; his aunt Jessica Phaneuf, her husband Adam, and their children AJ, Connor, and Reagan; his uncle Michael, his wife Katie, and their children Logan, Quinn, and Lucy; and his great-aunt, Amy Leduc. He was the grandson of the late James Stringer.
Mason will be remembered for his bright personality, kind heart, and the happiness he shared so freely. His memory will forever live on in the hearts of those who loved him.
His visitation will be held on Saturday, February 7, 2026, from 2:00 to 5:00 p.m. at the Waring-Sullivan Home at Birchcrest, 189 Gardners Neck Road, Swansea. All are welcome to attend and gather to celebrate his life. In lieu of flowers, donations in his memory may be made to The Tomorrow Fund.
