Jonathan William "Jack" Spang

Jonathan "Jack" William Spang, 32, of Winchester, Massachusetts, passed away suddenly on October 26, 2025, due to complications from diabetes, surrounded by his loving family.
Born on June 18, 1993, in Winchester, Jack was the beloved son of Pamela and Stephen M. Spang of Winchester. He was the cherished brother of Stephen F. Spang and his wife Cara of North Reading, Joseph Spang and his wife Louisa of Woburn, and Eric Spang and his wife Ariel of Calhoun, Georgia. Jonathan was a devoted uncle to his nieces Camilla and Emi and his nephew Duke, who brought him endless joy.
Jack will be remembered for his kind heart, easygoing spirit, and the deep love he had for his family. He enjoyed spending time with his brothers, parents, and nieces and nephew. As the youngest of four boys, his love of sports started early, reenacting WWE matches on the trampoline with his brothers. He could often be found making others laugh with his comedy routines or debating the latest sports news while cheering on his favorite Boston sports teams. A true fan through and through, Jack never missed a chance to talk about or debate the outcome of a game or the current team status of the Red Sox, Celtics, Bruins, or Patriots.
He will be deeply missed by all who knew and loved him.
A gathering of family and friends will be held at the Costello Funeral Home, 177 Washington St., Winchester, on Saturday, November 1, from 10 to 12, immediately followed by a Celebration of Life at the St. Anthony Club of North Woburn, located at 1020 Main St. Relatives and friends are kindly invited to attend.
In lieu of flowers, donations may be made in Jack's memory to the Joslin Diabetes Research Foundation, 1 Joslin Place, Boston, MA 02215, or online at https://www.joslin.org.
