About the Team


Our Center is a leader in fostering healthy lifestyles in the Kansas City community and around the world. We are dedicated to disseminating the latest knowledge regarding pediatric healthy lifestyles, from its biological origins to its societal impact.

The center focuses on major projects within our five key strategic focus areas: education, research, advocacy, community, and clinical. In 2021 our team secured over $57M in grant funding for this work across Children’s Mercy Kansas City and the University of Kansas Medical Center. Our 60 members bring our strategic goals into action every day through their rigorous, inclusive efforts of improving healthy lifestyles in all children and families.
