LOUDONVILLE, NY – The Siena University athletic department and the broader collegiate lacrosse scene are in mourning after the untimely death of Liam Gleason, the esteemed head coach of the men’s lacrosse team. Gleason, 41, succumbed to a severe traumatic brain injury on December 3, 2025, following a tragic accident at his home in Halfmoon, New York, just days earlier on November 30. His passing has elicited widespread tributes, highlighting his profound influence as a mentor, strategist, and family man.
The incident occurred when Gleason reportedly tumbled down a flight of stairs at his residence, resulting in critical head trauma. Emergency services responded promptly, performing CPR on-site before rushing him to Albany Medical Center for urgent care. Despite the best efforts of medical teams, his condition deteriorated rapidly. In a poignant final tribute to his generous spirit, Gleason, a registered organ donor, was given an “honor walk” through the hospital corridors as staff and loved ones paid their respects before organ donation procedures began—a fitting reflection of the selflessness that defined his character.
SUPPORT THE FAMILY - GOD BLESS YOU
Gleason’s tenure at Siena spanned seven transformative seasons, during which he elevated the Saints program to unprecedented success. Most notably, he led the team to a triumphant 2025 Metro Atlantic Athletic Conference (MAAC) title, clinching an NCAA tournament berth and earning him the prestigious MAAC Coach of the Year award. Players and assistants alike recall his infectious enthusiasm and relational coaching style. “Coach Gleason wasn’t just about wins; he built us up as people,” said a former Siena captain, speaking anonymously amid the grief. “His energy turned practices into something we looked forward to, and his guidance shaped our futures.”
Prior to Siena, Gleason honed his expertise at the University at Albany, where he excelled first as a player and then as associate head coach. His contributions were instrumental in propelling the Great Danes to six consecutive NCAA Tournament appearances, solidifying his reputation as a tactical genius in the sport. Colleagues from both institutions praised his ability to foster team unity and drive performance, often crediting him with turning potential into achievement.
At the core of Gleason’s life was his family, whom he cherished above all. He leaves behind his devoted wife, Jaclyn, and their three children: daughter Kennedy and sons Penn and Tate. The lacrosse community has rallied in support, with a GoFundMe initiative surpassing expectations by amassing hundreds of thousands of dollars in mere days to aid the family. Messages of condolence have flooded social media from alumni, rival teams, and national lacrosse associations, underscoring the far-reaching impact of his kindness and leadership.
A celebration of Gleason’s life is scheduled for Saturday, December 6, at 11 a.m. at the UHY Center on Siena’s campus. The event is open to the public, with university officials anticipating a large turnout from students, faculty, athletes, and fans to commemorate his enduring legacy. Counseling services have been made available through Siena’s wellness center to help the community process this profound loss.
As the lacrosse world reflects on Gleason’s contributions, his story serves as a reminder of the fragility of life and the lasting power of mentorship. Donations and further details can be found via the Siena Athletics website or the family’s support fund.
