Jill Hunsaker Ryan

Executive Director

Jill Hunsaker Ryan, MPH, is a public health professional with 28 years of experience in the field. She has been a local public health agency director, the vice president of the Colorado Board of Health, and previous director of the Department’s Office of Health Disparities.

From 2013 to 2019, Ryan served as an Eagle County commissioner, where she focused her efforts on determinants of health such as affordable health care and housing, environmental protection, climate action, emergency preparedness, and increasing mental health resources. In the same period, she also served as president of both the Colorado Communities for Climate Action (CC4CA) and Counties and Commissioners Acting Together (CCAT).

Ryan was appointed by Governor Jared Polis to take the helm of CDPHE at the end of January 2019. This was just over 13 months before the first case of COVID-19 was confirmed in Colorado. Ryan has helped lead Colorado through an unprecedented response, including the largest mass vaccination effort in Colorado’s history — an ongoing endeavor that has resulted in more than 4.5 million Coloradans receiving a COVID vaccine. 

Establishing greater health equity across populations is one of Ryan’s key goals for CDPHE. In 2020, the department joined the American Public Health Association and more than 100 cities, states and other public organizations to officially declare racism a public health crisis, as the root cause of health disparities. In 2021, CDPHE hired its first Equity, Diversity and Inclusion Officer, created a Communicable Disease Health Equity Branch to reduce disparities in COVID-19 and other infections, and established a new Environmental Justice Unit to reduce environmental health disparities for disproportionately impacted communities across Colorado. That same year, Polis and Ryan appointed members to Colorado’s first Environmental Justice Advisory Board, and CDPHE launched the new Environmental Justice Action Task Force. 

Another priority of Ryan’s is improving air quality. Under her direction, the department’s first climate action unit was created to help measure, track and reduce greenhouse gas emissions. She also initiated the department’s quest for tens of millions of dollars in new investments in the Air Pollution Control Division to reduce a historic backlog of permitting, modernize technology, and improve air monitoring to reduce pollution.

Ryan earned her undergraduate degree in psychology/sociology from the University of Colorado and a master’s in public health from the University of Northern Colorado. In 2020, she received the Albert Nelson Marquis Lifetime Achievement Award and the Denver Business Journal’s “Outstanding Women in Business” award for the health sector. In 2021, CiviCO honored Ryan with the Colorado Governors’ COVID-19 Heroes Award as an official who helped successfully lead Colorado’s pandemic response.

Director Ryan lives in Eagle County with her husband and school-age son. She enjoys the outdoors, playing piano and listening to live music.
