The lacrosse world is grieving the sudden loss of Siena University men’s lacrosse head coach Liam Gleason, a Long Island native who died after suffering a traumatic brain injury in a fall at his home. He was 41.

Gleason, who was originally from Wading River, leaves behind his wife and three children. His death has sent shockwaves through the Siena program and the broader Long Island lacrosse community, where he was known as both a fierce competitor and a guiding mentor.

“At a time like this, we’re all just trying to stay together and put one foot in front of the other,” said Siena player Will Miller, who also hails from Wading River. Miller described the tight-knit bond Gleason fostered within the team. “We’re all brothers. Coach G was like a second father to every one of us.”

Gleason led Siena to a standout season, capturing the Metro Atlantic Athletic Conference championship and earning an NCAA Tournament berth. His leadership, players say, extended far beyond the sidelines.

The sense of loss has reached hometown businesses as well, including Lacrosse Unlimited in nearby Miller Place, where players and fans expressed their grief. “Hearing the news is definitely devastating in the lacrosse community—especially him being from Long Island,” said Kamryn Gill of Riverhead.

Another local resident, Christopher Lore of Miller Place, recalled Gleason’s magnetic presence. “I had a little interaction with him, and when he walked into the room, it would just glow up,” he said.

A GoFundMe page launched to support Gleason’s family has already raised more than half a million dollars, reflecting the widespread affection and respect for the coach.

“He truly loved every one of us and was there for us on and off the field, 24/7,” Miller said.

The Siena men’s lacrosse team had been scheduled to hold its championship ring ceremony on Friday. Instead, players and coaches will gather Saturday for Gleason’s remembrance service.
