Between 1859 and 1874, Elsa Borg functioned as the principal of the Christian Girls' School in Gävle, regarded as the local pioneer secondary education institution for females in that city.
She ended her educational career in 1874 because she had become overworked, and retired to the home of her former colleague, the former teacher Alfhild Flodin, who married the businessman H. A. Lidholm and settled on the estate Nådhammar in Sörmland.
Elsa Borg accepted the offer to organize the project in Sweden, after making a study visit to the English role model in London.
[2] In 1875, Elsa Borg moved to Stockholm, where she founded a Bible Home for women with the support of Queen Sophia.
In 1877, it expanded to include an asylum for former female prostitutes, in 1881 an orphanage and in 1883 a hospital, and in 1885 a home for the education of missionaries: this was followed by branches in other parts of the country.
