Our Name.

Our name is a double entendre celebrating our roots in Hawaii and our connection to The Land Down Under.
Similar to the famous phrase “Hawaii No Ka Oi,” the word ‘oi’ in Hawaiian language means
“the best.” Our goal is to always recruit “the best” people that are committed to
producing “the best” results in a fun and
collaborative environment.
The word ‘oi’ is also Aussie slang to get one's attention. You're likely to hear Australian fans at a sporting match cheering “Aussie, Aussie, Aussie, Oi, Oi, Oi.”
Our job as communications specialists is to capture attention through standout initiatives that get people talking, posting, snapping, tweeting and sharing.
