About the Illustrator

Diana Thewlis

Vancouver, WA-based Illustrator Diana Thewlis began her pursuit of art at a very young age.  The daughter of an accountant at Washington DC’s Museum Labs, she grew up surrounded by artists and the fragrances of oil paint, turpentine, and clay.  Edwin Pearson, one of the contract artists there, came to live at her house and became her first mentor.


She studied Art at Montgomery College in Maryland under Dan Voss.  After receiving a degree in Commercial Art, Diana worked as a graphic artist, designer, product illustrator, and technical illustrator until she and her family moved to California, where she studied at the Academy of Art College in San Francisco under Barbara Bradley and received a degree in Illustration. 


She began a contract illustration career in 1980, creating illustrations for a broad range of commercial clients including Apple Computers, The United States Air Force, Houghton-Mifflin Publishing, St. Martin's Press, DelMonte, and Pillsbury. Diana has also painted for private clients, and for herself, whenever possible.


Her professional affiliations include the San Francisco Society of Illustrators, Society of Washington Artists, the North West Air Force Artists, the Society of Children’s Book Writers and Illustrators, and the Southwest Washington Watercolor Society.


Diana was asked to join the faculty at the Academy of Art College in 1992.  She has taught several courses at the Academy of Art University in the undergraduate and graduate programs including Clothed Figure Drawing 1 and 2, Illustration 2, History of American Illustration, Storyboard Drawing and Painting, Children’s Book Illustration and Watercolor for Illustrators.  It has been her pleasure to pass on her skills and knowledge to the next generation of artists.  She has written two online courses and continues to teach online from her new home in Vancouver, Washington. She has also lectured and taught workshops through different schools and organizations.


Diana now lives in Vancouver, Washington with her husband and is inspired to work on children’s books by her granddaughter, Zora.
