Born in El Salvador, Quest moved to the San Francisco bay area in 1982. He started out as a bedroom dj in 1987 and quickly began performing as a mobile dj. In the early nineties the second stage of his career took place when he began competing, producing and independently releasing turntable music. Quest is also known as one of the founding members of one of the original scratch crews in the bay area (Bullet Proof Scratch Hamsters/Space Travelers). In 1992, at dj battle that was staged for the popular tv show Home Turf, Quest gave birth to the term "Hamster Style" which refers to the reverse set up of the turntables. Today the term remains popular and is recognized by djs worldwide.

Quest and the BPSH produced "Hamster Breaks", the first record of its kind, designed specifically for scratch and battle djs. Since its release in 1993, hundreds of dj tool records have imitated the arrangement of this classic album. In late '96 Quest further expanded his musical horizons by teaming up with Albert Mathias (percussion) and Andrew Kushin (cotra bass) to form the experimental jazz/hip-hop group Live Human. In 2001 Quest won the SF Weeklys' "SF's Best Hip-Hop DJ" award.
