Trish Grantham began her painting career in Portland, Oregon in 1998. A self-taught artist, her distinctive illustrative style quickly gained recognition, leading to collaborations with brands such as Adidas, Target, Starbucks, Visa, Forever 21, American Greetings, Brooks Sneakers, Converse, and the School of Visual Arts in New York. Her work appeared on billboards in New York City, international product lines, and in exhibitions across the U.S. and abroad. She has shown with Augen Gallery in Portland, Mark Woolley Gallery, T&P Fine Art in Philadelphia, Museum Works in Los Angeles and New York, Gray Area in San Francisco, Rocket Gallery in Tokyo, Japan, and at major art fairs in London, Miami, and New York.

Her practice later expanded into interiors and design, where she became known for her hand-painted wallpapers and murals, featured at trishgranthamdesign.com.

Her current work is layered and dimensional, weaving vintage paper, wallpaper motifs, lace, and gold leaf into textured worlds where flowers, animals, and objects feel at once timeless and alive. These paintings are no longer flat illustrations but atmospheric spaces — windows into richly imagined rooms, each one offering a view into beauty, presence, and possibility.
