An icon of the sport, Gavin Arroyo enters his 18th season as the Head Men’s Water Polo Coach at Long Beach State. Arroyo has established himself as one of the premier coaches at both the collegiate and international level and was recognized for his excellence within the sport with induction into the USA Water Polo Hall of Fame in 2020.
This past summer, Arroyo completed a cycle with the USA Men’s National team, helping lead the squad to a Bronze Medal finish at the 2024 Paris Olympics, the first Olympic medal for the program in 16 years. That marked the second straight Olympic appearance for Arroyo, who also served as an Assistant Coach for the USA men at the 2020 Tokyo Olympics.
Arroyo has led Long Beach State to the NCAA postseason in two of the last five seasons, finished ranked in the Top 15 in each of the last 10 years and has posted a winning record in all but one season since 2011, ultimately compiling a 274-206 overall record as the head coach of the Men’s Water Polo program at the Beach.
In 2021, Long Beach State reached the NCAA Tournament after a dominant season. The Beach went 22-6 overall on the way to finishing the season ranked No. 6 in the nation and were a perfect 5-0 in Golden Coast Conference play before winning the GCC tournament. Rafael Real Vergara was named the Player of the Year, while Arroyo was named the conference Coach of the Year for the fifth time in his career.
That followed a tremendous 2018 campaign that saw Long Beach State win the Golden Coast Conference Tournament at the Ken Lindgren Aquatics Center. The Beach went on to host their first game of the NCAA Tournament, winning 12-5 against Pomona-Pitzer before falling in the National Quarterfinals in the program’s first tournament appearance since 1991.
Arroyo was named the Golden Coast Conference Coach of the Year and the Beach had five All-Americans in addition to GCC Tournament MVP, goalie Marwan Darwish.
Arroyo was a three-time MPSF Coach of the Year, earning the honors in 2007, 2012, and 2014. During the 2014 season he led the Beach to a 22-7 overall record and a 7-3 conference record. Long Beach State earned a No. 4 national ranking that season--matching the team’s final ranking in 2001 as the highest in program history.
In 2012 Arroyo led Long Beach State to a 24-8 regular season finish as well as a 4-4 finish in conference play. The historic year led LBSU to its first appearance in the MPSF Tournament since 2008 and ended with a fifth-place finish. Arroyo was also awarded with his second MPSF Coach of the Year award for his efforts.
In 2007, Arroyo was selected as the Mountain Pacific Sports Federation (MPSF) co-Coach of the Year after leading Long Beach State to a 17-15 record. During the 2007 season the 49ers upset No. 2 Stanford (7-5) in an MPSF home match and won the Inland Empire Tournament.
