William Shepherd was born and raised in Casper, Wyoming. As a child, he was attracted to the Native American and Western objects he would see in the homes of ranch friends. Following high school, he enlisted in the Navy and served in Vietnam. Afterward, he enrolled at the University of Wyoming in Laramie, Wyoming, and graduated with a Master of Fine Arts.
Shepherd’s professional art career began his senior year of college, when a gallery in Denver, Colorado, asked to represent his paintings. His early landscapes began as vistas of Wyoming that, over time, evolved into large-format oil paintings. After several decades of landscape painting, he began painting still lifes.
Shepherd’s paintings can be seen throughout the United States, Mexico, Europe, and Japan. The former Vice President and Mrs. Lynne Vincent Cheney recently purchased one of his rock paintings. He was invited to participate in the exhibit Out West: The Great American Landscape, which traveled to the National Art Museum of China in Beijing and the Shanghai Museum. In 2013, Shepherd was featured in a one-person exhibition at the Tucson Museum of Art in Tucson, Arizona.
