Katherine Castano is an artist, illustrator, graphic designer, and author residing in Snohomish, WA. Surrounded by llamas, cows, horses, and fruit trees, she’s constantly inspired by her environment.

Her creative journey started at a young age with an at home craft cart and by entering her hand painted picture books into local art competitions. After graduating college she worked for years in Graphic Design in the corporate world. She found it harder and harder to set aside her paints and pens and decided her true passion really was in illustration. To be able to draw & design for her job has been a lifelong dream and she’s so grateful for all of the opportunities that have come her way.

Katherine's designs can be found on greeting cards, puzzles, children’s books, and more. In 2024, Katherine published her debut children’s book, "Remy, Where Are You?", which she both wrote and illustrated. She describes her work as playful, sweet, and full of charm.

Her clients include American Greetings, Sourcebooks, Trader Joe’s, T.J. Maxx, Galison Puzzles, Hobby Lobby, Disney x Minted, Buffalo Games and Puzzles, and Wentworth Puzzles to name a few.
