Freier, who is also a grandmother, earned a degree from Brooklyn Law School while raising her family. She practiced law in New York and also served on the community board in Borough Park, Brooklyn.

Freier is highly respected for founding a secular academic program that helps ultra-Orthodox men who had only been educated in yeshivas (seminaries) to get a high school diploma, allowing them to go on to college or seek employment. She also founded Ezras Nashim (Help for Women), an emergency medical technician program designed exclusively to meet the needs of religious women in the community. Freier herself still remains on call for Ezras Nashim.
