Gleason’s journey in lacrosse began as a standout player at the University at Albany, where he helped secure an America East Conference title in 2007. That foundation propelled him into coaching, and by 2018, he had taken the reins at Siena, his seventh season culminating in a triumphant Metro Atlantic Athletic Conference championship and an NCAA Tournament appearance. His teams thrived under his guidance, not just in wins but in character-building moments on the field at Hickey Field in Loudonville.
Beyond the sidelines, Gleason was a devoted husband to Jaclyn, whom he married 12 years ago, and a proud father to daughter Kennedy and sons Penn and Tate. Colleagues described him as the kind of person whose handshake lingered in memory, a larger-than-life presence who made everyone feel seen. Siena athletic director John D’Argenio echoed this, noting the coach’s deep ties to the extended lacrosse family, including his time at UAlbany.
