She also took classes from Carleton Wiggins, Rufus Wright and Mauritz F.H. de Haas. She had already earned a reputation for landscape painting in Brooklyn before moving to California in 1897 at the age of 57, when she arrived with her brother, Charles Newhall, a roving missionary. After a brief stay in Redlands, she moved to Berkeley and opened a studio, and also studied with William Keith. She was able to support herself with her art, focusing on California scenes from Santa Barbara, Monterey, Lake Tahoe, and of course San Francisco Bay.
She exhibited with the Brooklyn Art Association, the San Francisco Art Association, the National Academy of Design, and the Art Association of Berkeley. She died in Berkeley in 1917 at the age of 77.
