Thomas (Tom) Edward Cosato Jr., age 53, of Plympton, MA passed away at his home on January 28th, 2026.

Tom graduated Silver Lake Regional High School in 1991, attending the school’s horticulture cooperative program. Tom was a lifelong resident of Plympton. At age 18, Tom became a member of the Plympton Fire Department, where he went on to serve as an EMT and firefighter for 20 years, reaching the rank of captain before his retirement. He was also elected as the town’s tree warden and served the position for 3 terms. Tom worked as a mechanic for Lesco and ran his own tree/landscape business for several years before his most recent employment with Norfolk County Agricultural High School. Tom was Norfolk Aggie’s equipment shop foreman for 20 years and retired early in July 2024 due to health issues. Tom had an incredible work ethic as a mechanic, EMT and firefighter, and was proud to serve his community. When he wasn’t putting out fires or turning wrenches, he enjoyed spending time with his beloved family, taking fishing trips with friends, and spending time outside. 

Tom is survived by his spouse, Melanie Dion-Cosato; his children, Richard Cosato, Shelbie Cosato, and Riley Cosato. His grandchildren, Lilliana & Marlee, his loving parents Thomas & Louise Cosato, and his brother Michael Cosato. Tom is also survived by many aunts, uncles, nieces, nephews, cousins and friends.
