Kori Mattisz

Manager of Programs & Client Relations

Kori’s roots in the nonprofit world began at the Indianapolis Art Center where she also found her love for office management—work that revolves around some of her favorite things, including organization, creative problem solving, and learning loads of information. She continued her administrative career in the for-profit sector, but as an Indiana native, she later felt compelled to return to work that had a more meaningful local impact, bringing her to LifeSmart Youth.
