She has addressed university student bodies, men in prison and in batterers' treatment programs, women at risk, church groups and various educational and legislative forums.

As part of her commitment, Ms. Brown has worked to help pass a variety of legislative solutions for domestic violence. One of her most important projects was to lobby on behalf of the Violence Against Women Act.

U.S. Senators Biden and Hatch have cited Denise Brown as "having done more for the issue of domestic violence than any other individual."
