[1] Maciariello's first coaching opportunity came with his alma mater as the director of basketball operations at Siena under Fran McCaffery in his first season at the helm.
He then went on to work with the Albany City Rocks AAU program until returning to the college coaching ranks in 2008 at Fairfield under Ed Cooley.
He'd follow Cooley briefly to Providence to serve as the director of operations, but would ultimately take an assistant coaching position at Boston University in that same offseason.
Despite the cancellation of the tournament, Maciariello became just the second coach in program history to earn a berth to the NCAA tournament [citation needed] in his first season as head coach, and was the first in program history to win the MAAC regular season title in his first year.
After the only losing season in his head coaching career, Siena parted ways with Maciariello on March 20, 2024.
