Noe Ruiz Jr. was named a Volunteer Coach for the Islanders in Aug. 2022 and was elevated to Assistant Coach after the 2023 season. The 2026 season will be his fourth season with the Islanders.

To start off his tenure with the program, Ruiz helped the Islanders qualify for the Southland Conference Tournament in each of his first three seasons. In 2025, the team entered the postseason as the No. 7 seed and eliminated third-seeded Lamar from the bracket in its second game of the Edinburg Bracket.

Ruiz spent the previous four seasons at Eastern Oklahoma State as an assistant coach under Matt Parker, who was announced as an assistant coach the week prior with the Islanders.

While with the Mountaineers, Ruiz helped the team to a 142-39 record and two NJCAA Region II Regular Season and Tournament Championships in 2021 and 2022. Alongside Parker, Ruiz had one player drafted in the MLB Draft in the seventh round and has seen numerous other athletes succeed under him.

Ruiz followed Parker from Oklahoma Wesleyan where he served as an assistant coach and recruiting coordinator. The team made appearances in the NAIA World Series in 2014 and 2017 along with winning the Opening Round Regional Championship in both years.
 
His time at Oklahoma Wesleyan helped the program oversee 68 All-Conference Performers, 19 Conference Gold Gloves as well as two Conference Freshman of the Year and one Conference Newcomer of the Year accolades.
 
Ruiz earned his bachelor's degree in fitness and sports at Texas A&M-International before obtaining his master's in business administration from Oklahoma Wesleyan.
 
A native of San Antonio, he now resides in Corpus Christi with his wife Rebecca.
