LOUDONVILLE, N.Y. — Liam Gleason, the head coach who revived Siena men’s lacrosse, has died at 41.
The Coach passed away at Albany Medical Center after sustaining a traumatic brain injury when he fell at his home in Halfmoon. He died three days after the accident.
The fall reportedly occurred on a Sunday afternoon when Gleason fell down a flight of stairs and suffered a serious head injury.
Emergency responders performed CPR while he was transported to the hospital.
Siena called the loss sudden and senseless and asked for privacy for the family. The College Wrote,
“We are heartbroken to share the tragic news of the passing of men’s lacrosse head coach Liam Gleason. All are welcome to join us for a funeral service to celebrate Coach Gleason’s life on Saturday at 11 AM in the UHY Center. We love you, Coach.”
A True Professional Gone Too Soon
Gleason took over the Saints program in June 2018 and changed the culture fast. Over seven seasons, he rebuilt the roster, developed young players, and guided Siena back into contention.
In 2025, the team won the Metro Atlantic Athletic Conference championship and earned a berth in the NCAA Division I tournament, the program’s first conference title in more than a decade.
Wins mattered to Gleason, but so did development and accountability. Under his leadership, Siena produced multiple all-conference players and earned regular academic honors.
Former players and assistant coaches credit him with building a program that prepared athletes for life beyond the field.
Sienna Saints wrote, ““A sudden, senseless loss carries a kind of pain that defies understanding. It’s hard to imagine anyone more universally loved and admired than Liam. Coach Gleason’s life blessed our community.”
Scott Marr, a former college coach, also remembered, “He was a lot of fun, smiled all the time. Extremely positive person. He had just a wonderful heart. His love was his kids. I feel so badly for his wife and his kids now.”
A Long Island native, Gleason played college lacrosse after transferring from Division II Adelphi to the University at Albany.
He appeared in 28 games for Albany and was later selected in the 2007 supplemental draft for Major League Lacrosse.
He began his college coaching career as an assistant at Siena, later led Saint Rose, spent time on staff at Albany, and returned to Siena as head coach in 2018.
He is survived by his wife, Jaclyn Rosada, a former University at Albany women’s soccer player, and their three children, Kennedy, Penn, and Tate.
The couple had been married for about 12 years. In the days after the accident, a fundraiser to support the family drew an immense outpouring from the lacrosse community and beyond.
Siena officials and regional programs organized tributes, including hospital honor walks and on-campus gatherings, as players, alumni, and rival teams paid respects.
Colleagues remembered Gleason as a mentor who expected hard work and returned that trust with genuine care.
For a region that treats lacrosse like family, this is a profound shock. The Saints are left with a program on the rise and a hole that will not be filled quickly.
The memorial on December 6 will be the first public chance for the community to gather and honor the coach whose work changed a program and many lives.
