Former Irvine Valley standout Nick Costello returns to the Lasers, but this time as part of the coaching staff.

He spent the past two seasons as the Volunteer Assistant at the University of Hawai’i under coach Robyn Ah-Mow.

During that span, the Rainbow Wahine program made back to back appearances (2017-18).

Castello, a Hawai‘i alum, was the starting libero for the Rainbow Warriors volleyball team from 2011-12.

He finished his UH career with 404 total digs (1.99/set).

As a senior, he averaged 2.28 digs per set which ranked 14th nationally and fourth in the Mountain Pacific Sports Federation.

After graduating from Hawai‘i in 2012, Castello went on to play professionally for VK Ostrava (2013-14), which competed in the CEV Champions League and then for Voleibal Brno (2014-16), the latter of whom he helped win silver at the Czech Extraliga Cup and silver in the Czech Extraliga.

Prior to playing at UH, Castello played two seasons at Irvine Valley and was a member of the 2010 Pacific Coast Athletic Conference championship squad.

He was named the conference’s player of the year in 2010 after averaging 4.03 digs per set and was also selected first-team all-conference in 2009.

The Honolulu native is a 2007 graduate from Assets High School.

Castello starred at Maryknoll School because Assets did not field a volleyball program.

He earned second-team all-state and first-team all-league honors as a senior. He also played basketball and baseball in high school.
