In 2010, Librepensadores de Washington DC formed as an informal social group in an effort to attract and educate Hispanic Americans about critical thinking skills, skepticism, and the questioning of supernatural claims. Ten months later, the group decided to formalize the organization registering as a non-profit corporation. Almost immediately, the group voted to rename itself to Hispanic American Freethinkers, Inc. and to focus not just in the Washington, DC area, but the entire United States of America.  At this time the IRS approved their non-profit 501(c)(3) status, which they’ve kept current ever since. After eight years, HAFree keeps working forwards its goals. ​

We believe all women can embrace who they are,
can define their future, and can change the world.

Our Mission

The mission of the non-profit educational organization known as Hispanic American Freethinkers, Inc. (HAFree) is to serve as a resource and support to all Hispanic freethinkers in promoting the search for truth through science, rational thought, skepticism, humanism, logic, and the scientific criticism of all un-natural (i.e. supernatural) claims and dogmas. It encourages the rational evaluation of faith-based myths, the support of the Constitutional idea of state and church separation, secular values, promotion of critical thinking in general as well as absolute freedom of conscience. 


Our Vision

We are working on making our organization a platform for all Latino communities in America where we all can share our knowledge and grow up together as a family
