Siena men’s lacrosse coach Liam Gleason died Wednesday, days after he fell at his home and suffered a traumatic brain injury.

He turned 41 last Friday, two days before the accident at his house in Halfmoon, N.Y., a suburb of Albany.

“A sudden, senseless loss carries a kind of pain that defies understanding,” said Chuck Seifert, Siena’s president. “It’s hard to imagine anyone more universally loved and admired than Liam. Our community was blessed by Coach Gleason’s life.”

Condolences poured in from the lacrosse community nationwide to the tight-knit college community locally. Youth and college lacrosse programs across the country donated to a GoFundMe account set up to benefit Gleason’s wife, Jaclyn, and their three young children.

Gleason was a 2007 graduate of Albany, playing for the Great Danes, then accepted his first assistant coach job at Siena — just seven miles away — the following season. He later became the head coach at Division II St. Rose and returned to Albany as an assistant coach before being named head coach at Siena in 2018.

He led the Saints to the Metro Atlantic Athletic Conference championship in May and was named conference coach of the year.

“Liam was a tremendous coach, a passionate competitor, and a respected colleague within the conference,” MAAC commissioner Travis Tellitocci said. “He was a bright, rising leader in the men’s lacrosse community.”
