Our Mission
Launched in 2006, the Appignani Humanist Legal Center (AHLC) is the legal arm of the American Humanist Association. The AHLC’s team of attorneys, through trial and appellate litigation, amicus activity, and other legal work, provide the zealous advocacy that humanists and others need to defend constitutional rights and strengthen the wall of separation between church and state.
Our legal staff includes senior staff attorney Katie McKerall paralegal Stephanie Hansen, plus a network of volunteer attorneys from around the country, including humanist luminaries such as Jim McCollum, Wendy Kaminer, and Michael Newdow. Guidance and funding for the center come from Louis Appignani.
