PHOENIX, AZ — Sean William Gallagher, a respected golf industry professional, custom club maker, and former collegiate athlete, passed away on Tuesday, March 10, 2026, following a brief illness. He was 35 years old.
Residing in Phoenix, Arizona, and formerly of Topsfield, Massachusetts, Gallagher built a career defined by technical precision, athletic leadership, and an unwavering commitment to his community. His professional journey—spanning elite turf management for major championships to the meticulous craft of custom golf club fabrication—leaves a legacy of excellence within the sporting world.
Early Life & Education
Sean William Gallagher was born on July 23, 1990, in Beverly, Massachusetts, to Suzanne and William Gallagher. Raised in the town of Topsfield, he exhibited an early aptitude for competitive athletics and team dynamics.
He attended Masconomet Regional High School, graduating in 2008. During his high school tenure, Gallagher distinguished himself as a natural leader, serving as the co-captain of both the varsity basketball and lacrosse teams. His athletic prowess and strategic understanding of team sports led him to Curry College in Milton, Massachusetts. There, he earned a Bachelor of Arts degree while continuing to demonstrate exceptional leadership as the co-captain of the Curry College men’s lacrosse team. These formative years in competitive sports instilled in him a deep understanding of biomechanics, discipline, and collaborative success—principles that would later become the foundation of his professional life.
