About CHORDS

Public health and health care experts conceived and created this groundbreaking tool in 2011 to provide location-based information on population health measures in the metro Denver area. CHORDS expanded to Larimer and Weld counties in 2018.

CHORDS aggregated medical and behavioral health data from 14 contributing providers. CHORDS partners shared their learnings to inform future work. Links to additional CHORDS resources including governance documents, publications, and presentations featuring CHORDS data are posted below.

CHORDS is no longer providing updated data. Please contact Nina Bastian with questions.
