After graduating from high school he decided to attempt a career in journalism, and began by selling photographs to various magazines, including Popular Science, Scientific American, and Popular Mechanics, and then received a few assignments to write articles. Advised that a journalist needed formal study, he moved to Santa Maria, California where he enrolled in what was then called Santa Maria Junior College. During his year there he took a room in the home of two art teachers who recognized his talent and encouraged him to become a painter, but he was resistant. Instead, he decided to study architecture, and he moved to San Francisco.
In 1927, he attended Otis Art Institute (now Otis College of Art and Design) where he studied with Millard Sheets and F. Tolles Chamberlin. He later taught at Otis. For 12 years he was art director for the Padua Hills Theater in Claremont, California.
