What we’re about

If you don't believe in supernatural entities or powers, if you are concerned about religious intolerance or religiously motivated violence, if you rely on human reasoning and science to guide your decisions and behavior, if you have a naturalistic view of the world, or you just don't believe in God or gods, you are not alone. The Boulder Atheists group provides presentations, meetings, and serves as a social community for atheists, agnostics, rationalists, secular humanists, Brights, and free thinkers in and around Boulder, Longmont, Lafayette, Broomfield, and surrounding communities in Northern Colorado.

Boulder Atheists wish to promote the understanding and acceptance of atheism with public education, good deeds, public activities and affiliations with other local and national secular groups. We strive to be inclusive to ALL and promote gender equality, LGBTQ equality and racial justice.
