Marjorie Dannenfelser, an original organizer of the SBA List, is the organization's President and Chairman of the Board. As President, Marjorie directs the mission of Susan B. Anthony List, is the chief strategist, and serves as its primary spokeswoman. Under her leadership, the organization has grown to over 280,000 members nationwide.

Since its founding, the organization’s connected political action committee, the nonpartisan Susan B. Anthony List Candidate Fund, has helped elect 75 pro-life candidates to the U.S. House of Representatives, seven to the U.S. Senate, and seven to other statewide offices across the country.

This year, the Susan B. Anthony List has lead the fight to keep abortion out of health care reform. Already this year Susan B. Anthony List activists have sent nearly one million letters to Congress to defend women and unborn children. As part of its new Votes Have Consequences Program, the Susan B. Anthony List is challenging targeted legislators nationwide to vote pro-life on health care through television ads, radio ads and targeted grassroots efforts.

Marjorie has represented the Susan B. Anthony List on Fox News (The O’Reilly Factor, Your World with Neil Cavuto, America’s Newsroom), CNN, CBN and EWTN. She often appears on both regional and national radio shows, including Janet Parshall’s America, Catholic Connection with Teresa Tomeo, The Fred Thompson Show, and the Bob Dutko Show. She is a regular contributor on pro-life political issues to national radio news services, like Focus on the Family Radio, American Family Radio, and Salem Radio News. Her commentaries have appeared around the country and have been published in The Weekly Standard, National Catholic Register, The Washington Times, National Review Online, Townhall.com, The San Francisco Chronicle, The DC Examiner and many other periodicals.

Prior to launching the Susan B. Anthony List, Marjorie served on Capitol Hill as staff director of the Congressional Pro-life Caucus. Previous to her work on Capitol Hill, she worked at the Heritage Foundation. She is originally from North Carolina and is a graduate of Duke University. Marjorie lives in Arlington, Virginia with her husband Marty and their five children, ages 8-17.
