Sister Cities – Cheyenne and Arapaho Tribes is a Broomfield-centered, citizen-led effort that re-examines local, state and U.S. history and seeks to build meaningful connections between Native and non-Native people, in our area and beyond. We are the second Sister Cities-focused group in Broomfield alongside the long-running partnership with Ueda, Japan, and we are working toward the formalization of a Sister Cities relationship between Broomfield and the Cheyenne and Arapaho Tribes, headquartered in Concho, Okla.

Our group was born in 2019 out of an advocacy effort called “Confluence” within The Refuge in Broomfield. While we officially affiliated with the Broomfield Council on the Arts and Humanities in late 2023, we count The Refuge, the City and County of Broomfield and other community groups among our partners and allies.

Upcoming Meetings
