Hillary Cook joined the Chicago Learning Exchange team in October 2022 as the Director of Programs. In this role, Hillary leads CLX's programmatic portfolio of collective learning and impact programs, community building and network opportunities, and special events that amplify and invest in the work of Chicago's youth development professionals.

Prior to joining CLX, Hillary worked in youth development for 14 years, building programs that centered youth voice and leadership within art museums. Her practice as an informal educator and programmer was driven by co-creating with communities, platforming the power of youth voice, and creating equitable career and mentorship programs. As a Chicago youth development professional, Hillary actively participated in CLX. Those experiences as a network member were transformational for her practice as an educator, and allowed her to see the power of social impact networks in action.

Hillary studied at Penn State University and the School of the Art Institute of Chicago, earning degrees in Art Education, Painting, Art History, and Arts Administration. Celebrating the power of creativity and youth voice are also at the center of her collaborative practice at home as a mom to two messy and energetic kids.
