During the renovations, both basketball teams played at Pritchard Gymnasium, which like the Island Federal Credit Union Arena, is part of the Stony Brook Sports Complex.

[12] The old arena contained gaps in the seating bowl, and the renovation faced challenges due to the physical limitations of the original structure.

[13][14] The arena hosted its first home basketball game on November 14, 2014, and Stony Brook defeated Columbia 57–56 on a game-winning layup.

[15][16] On October 28, 2014, it was announced that Stony Brook had reached a deal with Island Federal Credit Union to purchase naming rights to the arena for $7 million.

Concerts in the 2000s were sparse, with only 3 Doors Down & Oleander (2000), Sugar Ray (2001), Kanye West (2004), and Jimmy Eat World & Taking Back Sunday (2005) headlining during the decade.

[20] Speakers include Supreme Court associate Justice Sonia Sotomayor, author Janet Mock and designer Joshua Davis have held talks at Island Federal Arena.
