About Us

Siouxland Freethinkers is a community of atheists, agnostics, humanists, and skeptics.

We encourage and support critical thinking skills, science based methods of inquiry, unfettered by supernatural beliefs or dogma. We also support our secular form of government as a necessary condition for the interdependent rights of freedom of religion and freedom from religion.

We conduct a variety of formal meetings, outreach, and social gatherings to foster relationships with like-minded people.
