As part of the Women's Improvement Club, Porter established Oak Hill Camp, which is believed to be the first outdoor tuberculosis treatment facility in the United States.

[3] Porter left her medical practice in 1901, a change some historians attribute to the reluctance of patients to be treated by an African American woman doctor.

[1][4] Also in 1905, Porter represented Indiana and presented a paper at the Colored National Teachers Convention in Atlanta, Georgia.

By 1910, Porter was no longer living with her husband, and was listed as a boarder at the house of African American physician Joseph H. Ward.

The couple lived in Indiana Avenue, an African American neighborhood in Indianapolis, until the 1920s, when they moved to Boulevard Place.
