Cultivating healthy living through partnership and discovery
The Vanderbilt Children’s We Grow Healthy Center is dedicated to improving child and family well being through community engaged research that grows from shared effort. We believe healthy living takes root when evidence, family strengths, and community resources work together—so we design every project with real world experiences at the center.
Our work is deeply informed by the “kids in context” approach championed across Vanderbilt Pediatrics, ensuring our research reflects the environments where children spend their lives.

Mission
To cultivate healthy living by conducting rigorous, community engaged research that elevates family strengths, advances discovery, and translates evidence into action across clinical, home, and community environments.
Vision
A future where every community has the partnerships, tools, and evidence needed to help children grow healthy—because research is created with families, rooted in children’s real world contexts, and scaled across systems to support wellbeing.
Our Story
The We Grow Healthy Center began with a simple belief: healthy living flourishes through shared effort. Originally a research group focused on family centered interventions, our team grew into a center committed to cultivating health through partnership and discovery.
Embedded within Monroe Carell Jr. Children’s Hospital at Vanderbilt and the Department of Pediatrics, we align with the institution’s commitment to groundbreaking discovery, training the next generation, and extending impact beyond hospital walls.
Today, we bring together scientists, clinicians, families, and community organizations to co design interventions, build programs families can use, and share findings that strengthen communities.
