Olivia Hill was born in Chicago to an artist mother and writer/musician father. When she was two-years-old her family moved to Los Angeles. Hill's journey as an artist began in earnest upon acceptance to the Los Angeles County High School For The Arts (LACHSA), a public magnet school where she studied visual art. In 2006 she received her BFA in painting at the San Francisco Art Institute and in 2020 she completed her MFA at The University of California, Riverside.
