Sensei Joey to Represent the United States at K-1’s “World Max Final 16”

From September 4, 2013 Press Release

Riverside native Joey Pagliuso has risen to the kickboxing world's elite ranks. Pagliuso will be representing the United States in the prestigious K-1 "World Max Final 16" in Mallorca Spain on September 14, 2013. K-1 has, for nearly 20 years, held tournaments in 38 countries. As the first American fighter in over 10 years to advance to the K-1 Final 16, Pagliuso is also only the second US fighter to ever qualify.

USKO Corona class

The son of Joe & Sandra Pagliuso, founders of Riverside's respected USKO Martial Arts Schools, Joey is married to the reigning Mrs. Riverside - Desiree Pagliuso-Nava. Joey grew up learning Karate from the time he could walk, and graduated from Riverside's Ramona High School.

A longtime fan of K-1, Joey hoped to one day fight for the promotion. Then, after a number of years fighting on the Muay Thai circuit, in the fall of 2012 Joey was invited to fight in K-1's celebrated return to the US - "K-1 Rising" at the LA Sports Arena. With a KO win over Ben Yelle at "K-1 Rising", Joey moved on to the K-1 World Max Qualifiers in Calgary Canada, where he defeated Canada's own Mukai Maromo via knockout.

Now, on September 14th from Mallorca Spain, and streaming live via Epicentre.tv, Pagliuso hopes to be the first US fighter to move beyond the round of 16 in the K-1 "World Max" Championship Tournament.
