In 1892, Nystrom had become a member of the general board of what was then called the Young Women's Mutual Improvement Association. She became its corresponding secretary in 1904, and then its treasurer.[1] She continued in this position until 5 April 1905, when she was chosen by new president Martha H. Tingey as the second counselor in the organization. Nystrom was a counselor to Tingey until she was released on 15 July 1923 because of her move to Green River, Wyoming. She was succeeded in her position by Lucy Grant Cannon. Nystrom returned to live in Salt Lake City in 1929.
