Airin O'Callaghan was born in Boston, but her family moved to Barcelona only 6 months later, to be where her parents were from. Since then, she has lived in the Netherlands, attending the University of Amsterdam, and then San Francisco, where she earned her MFA in illustration. Her inspiration comes from her early childhood in Spain, where she spent a lot of time surrounded by family and playing in nature. Her family is very warm and expressive, and her grandmother taught her to pay a specific kind of attention to detail. Airin lives in Berkeley, California.
