Trudy Foster began attending early meetings of the Denton Women's Interracial Fellowship (DWIF) in 1964. She was described as a "force to be reckoned with" and was determined to motivate the City to pave Southeast Denton's streets where most African American citizens lived. Prior to her involvement, the streets filled with mud after rain and had no sidewalks. Trudy was persistent and vocal when advocating for improvements in City Council meetings, never taking no for an answer.
Prior to moving to Denton, Trudy lived as a Christian missionary in what would later become Pakistan, an experience which sensitized her to inequality. Having herself experienced the subjugation of religious minority status overseas, she clearly saw injustice in the way African American communities were treated in the U.S.
