The Monsters were announced in Spring 2009, filling a void for hockey in Fresno after the Fresno Falcons folded. The team began play in mid-September 2009, playing in the Tier III Jr. A Western States Hockey League. On December 15, 2009 the Monsters announced the organization was given expansion approval into the Tier II North American Hockey League for the 2010–11 season and Fresno would host two levels of junior hockey for the first time.
On May 23, 2013, it was revealed the Monsters' North American Hockey League franchise would move to Wenatchee, Washington and become the second Wenatchee Wild. The Monsters continue to field a team in the Western States Hockey League.
In the summer of 2015, The United Hockey Union (UHU) announce that the Western States Hockey League (WSHL) would now be competing in North America as a Tier II hockey league in the UHU.
On March 22, 2016, after six seasons coaching the WSHL Monsters, head coach and general manager Bryce Dale stepped down from his positions with the organization.
On June 1, 2016, it was announced that The Central Valley Community Sports Foundation, led by Jeff Blair, had acquired the team and former Assistant Coach Jason Rivera would be taking over as General Manager & Head Coach.
At the end of October 2016 it was announced by ownership that Jason Rivera would be replaced by former Washington Capitals, Kevin Kaminski, as Head Coach & General Manager.
TEAM COLORS - BLACK & GREEN
Green is to pay homage to the teams roots in the Central Valley and it's rich agriculture heritage. The Gold accent is to pay homage to the team that paved the way for hockey in Fresno, the Fresno Falcons.
And Black.... Black is for attitude.
DEKE' THE MONSTER
Deke was adopted as the Monsters mascot since the inaugural season in 2009.
Legend has it that Deke was once a very successful hockey player who came up through the jr. program here in Fresno. He volunteered as part of a scientific research group whom were looking to create the perfect hockey player. They developed a PAX known as PAX G-23 but the experiment failed and left Deke with his current appearance.
