Oster was born in Los Angeles, California.
Prior to his comedy career, Oster was a Universal Studios tour guide and a karaoke jockey. He first discovered his love for improv during his senior year of high school, when his girlfriend at the time took him to see his first live improv show. Upon learning the troupe responsible for the show, Ultimate Improv, was offering paid workshops to foot the bill for their theater space, Dan decided to take the plunge and sign-up.
This led to an impressive five-year tenure with the Ultimate Improv, which ended when Oster joined in July 2005.
During his time with, Dan co-wrote and performed in one of the troupe"s biggest hit shows to date: "Maine, MySpace and iPod". This send-up of the digital age was hailed by many critics as "the best show ever" in addition to becoming the longest-running show in the theater"s 15 year history.
Between major productions, Oster found himself trying a bit of everything by way of his fearless stage persona, from jokingly discussing penile inadequacy to performing freestyle raps as obscure popular culture icons like Paul Reiser and Cobra Commander from G.I. Joe. Outside the Boom theater, one of Dan"s most noteworthy pre-gigs came in the form of a 30-minute mockumentary-style television program entitled "The Digital Difference".
