In the 1920s and 1930s, Sundstrom maintained a busy performing schedule, regularly appearing on stages in Chicago and Minneapolis, and in live radio concerts. She also taught violin at the
Bush Conservatory of Music in Chicago. In 1929, she took over from
Ethel Leginska the director position with the Woman's Symphony Orchestra of Chicago. After seven seasons conducting the orchestra, she took leave in 1937 for "study and travel". She did not return to the conductor's post, but by 1941 was teaching at
North Park College, and conducting the school's orchestra, until she resigned from North Park in 1951. Sundstrom often played with and for Swedish-American cultural groups, including the United Swedish Singers of Chicago, The Swedish Old People's Home Society, and the American Daughters of Sweden. She was one of the first members of
Altrusa in Chicago, and appeared on Altrusa programs as a presenter. She was president of the Women's Music Club. ==Personal life==
