After his time with Skankin' Pickle he went on to found Asian Man Records, a label which he has run out of his garage in California since 1996 with only help from his parents and friends. Asian Man Records supports mostly ska and punk bands. Park will support any band as long as it is "anti-racist, anti-sexist, and anti-prejudice".
