After a tremendous amount of interest on campus, Williston added Ultimate to its sport offerings in the spring of 2013. Since then, Ultimate has grown into a strong program, including an undefeated season (2021), a middle school team (2022) and a NEPSUL Championship (2022). The team welcomes all interested players to the program regardless of experience, with the majority of participants learning the sport at Williston. The team competes in a number of matches in the spring season against public and private schools. The team also competes in 2-3 tournaments during the season, including the New England Prep School Ultimate League Championships. The values of sportsmanship and teamwork are of utmost importance to the program.
