Robert Pummill's career path has been multi-faceted, including a short stint as a sign painter, a printed circuit designer at a computer company, and an illustrator at TRW Systems in Los Angeles where he worked on the Voyager project. He was able to devote full-time to painting in 1977 and was a member of the Cowboy Artists of America from 1984 to 2005.

In the course of his career, Pummill has drawn inspiration from a wide diversity of western themes. Reflecting, he notes, "The time period I focus on is the 1840's to 1900's. I'm particularly attracted to the early cattle industry, the trail drives and the long horn cattle, although recently I've done more Native Americans.

"Someone once said, 'Choose an occupation you like and you will never have to work.' That makes me one of those lucky people. I am very aware that this would not be possible without great collectors. Subject matter must be sensitive to the buyers taste. Technique and the quality of the work must be the artist's priority."
