Cassidy Spilis

Cassidy Spilis joined the Stony Brook women's lacrosse coaching staff in July 2026. Spilis assumed the role of defensive coordinator and also serves as the team's draw coach.

Prior to Stony Brook, Spilis was an assistant coach at the University of Southern California from 2024-26. While at USC, she had a hand in coaching both the offensive and defensive units, while also specializing at the draw. Spilis helped the Trojans to an 18-16 overall record in their first two seasons as a member of the Big Ten conference.

Prior to USC, Spilis starred at Rutgers as a student-athlete. A three-time IWLCA All-American (2021, 2022, 2024) and a two-time unanimous Big Ten Midfielder of the Year (2022, 2024), Spilis' accolades also include four All-America selections by Inside Lacrosse (2021-24) and three by USA Lacrosse Magazine (2022-24).

Spilis was a three-time team captain for the Scarlet Knights (2022-24) and was a four-time All-Big Ten First Team selection, the Big Ten All-Tournament Team honoree, and the Big Ten All-Academic Team member. In 2024, she received the Big Ten’s Medal of Honor. She was also a four-time IWLCA All-Region team member and a four-time nominee to the Tewaaraton Award Watch List, landing on the top 25 list twice (2022, 2024).

Spilis completed her collegiate career as Rutgers’ all-time career leader in points (281), goals (266) and draw controls (313). In her final season, she broke her own record to set the Knights’ single-season goal record at 74 (2024).

Following her collegiate career, Spilis was selected 13th overall in the AU Pro Lacrosse Draft and trained with the U.S. Women’s Sixes National Team. She is currently competing in the inaugural summer season for the professional Women’s Lacrosse League (WLL) with the Maryland Charm.
