Sydney Hanson is the illustrator of Construction Cat by Barbara Odanaka and I Am Not Happy! and I Am Not Grumpy! by Caroline L. Perry. She was raised in Minnesota alongside numerous pets and brothers. When she wasn’t tunneling through snowdrifts or rescuing frogs from rain gutters, she was drawing. Her illustrations and paintings still reflect these early adventures and are marked by a love for animals and the natural world. She lives in Los Angeles where she’s worked for several animation shops. In her spare time, she enjoys traveling and spending time outside with her adopted brother, a Labrador retriever named Cash.
