Her father was Joel Frederick Vaile, a national authority on general business, mining, and railroad law.

[9] After her mother's death,[10] she then spent several years at home housekeeping,[11] and was active in various club and philanthropic societies.

She then entered definitely into the employ of the United Charities, first as a "visitor,” investigating cases of need and carrying out the treatment decided upon by the District Superintendent.

She served as one of the investigators in a study that the Russell Sage Foundation made of the operation of the Mothers' Pension Law in Illinois.

[4] Back in Denver by 1916, she served as Executive Secretary, Bureau of Charities and Correction,[14] and was still in that position in 1925.

[15] It was reported in 1919 that through Vaile's efforts, the public poort department of Denver was socialized and converted into a modern progressive organization.

[16] Vaile was the western states field representative of the American Association for Organizing Family Social Work for four years, resigning in 1923, which was occasioned by her desire to settle down in one community.
