Carmen Maciariello

In 2018, Maciariello returned to his alma mater as an assistant coach under Jamion Christian. He was elevated to head coach on March 25, 2019 after Christian accepted the head coaching position at George Washington, making him the 18th head coach in Siena basketball history.

In his first season, he led the Saints to the #1 seed and a regular season championship for the first time since 2010. The Saints entered the MAAC tournament as heavy favorites to advance to the NCAA tournament, Manhattan coach Steve Masiello, went as far to reference the tournament as "The Siena Invitational". In their first game at the MAAC Tournament, the Saints easily defeated Manhattan 63-49. Shortly before their semifinal, the MAAC was forced to cancel the tournament due to the COVID-19 pandemic. As regular season champions, the MAAC announced Siena would be named Conference Champions and were awarded the conference's automatic bid to the NCAA tournament. It was Siena's first bid since winning three consecutive MAAC tournaments between 2008-10. The tournament was later cancelled along with the remainder of the college basketball season as a result of the outbreak.

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. After two years at BU, Maciariello joined the staff at George Washington, where he was on staff for the Colonials' 2016 NIT Championship.
