John Gabriel Rosenberg

John Gabriel Rosenberg, 80, of Vonore, Tennessee, passed away on March 11, 2026, after a courageous battle with cancer. Born in Detroit, Michigan, on December 12, 1945, to Sidney and Paula Rosenberg, John graduated from Mumford High School and attended Eastern Michigan University before serving as a Lieutenant in the United States Army. He completed a tour of duty in Vietnam from 1969 to 1970 and was awarded the Bronze Star for his heroic service in combat.
