Our Team


Shelly Casto

Executive Director

Shelly has 30 years of experience in nonprofit leadership, primarily in the arts. In recent years, she developed a specialty in studying and working with contemporary artists who focus on issues of ecology and food justice. That led her to spearhead the construction of two “fruit parks” in Columbus with the artist collective Fallen Fruit: the South Side Fruit Park on Reeb Avenue and the Weinland Park Berry Patch at 11th and 4th. She holds a BA in Art History from Oberlin College and an MA in Art Education from the Ohio State University. She is a beginning gardener and an expert home cook.
