She joined the Midnight Star Concert Company in 1883, touring as a singer with the company. She later joined a concert company as their prima donna soprano and began touring in California.
In 1895, Walker moved to New York for her career. She traveled to London in 1897 and began living abroad until the onset of World War I, eventually returning to the United States in 1915.
