November is officially designated as Native American Heritage Month, in which we celebrate our rich heritage and historical achievements including modern day successes in higher education and building stronger economies.

Generous sponsorships from Avista, Central Washington University, the Colville Tribes and WSU Spokane are helping us spread awareness of our important place in the history of our country, and our continuing contributions.

Join us as we celebrate Native American heritage and achievement all November. Because it’s not just a celebration of our past; it’s a celebration of our future.
