Lia Halloran (born 1977) is an American painter and photographer who lives and works in Los Angeles.
Born in Chicago, IL., Lia Halloran grew up in the San Francisco Bay Area town of Pacifica, CA. Her youth was spent skateboarding and surfing, first given a skateboard at the age of five, and at the age of 15 was featured in Thrasher magazine. She developed an early love for science during high school at her first job, where she performed cow eye dissections and laser demonstrations at the Exploratorium in San Francisco. Her love for skateboarding, surfing, and science would later play an important role in her own understanding of art and creativity.
