Raised in the South, Katherine has spent the last two decades working in all aspects of fundraising at mission based organizations geared towards equitable education, youth development and the arts. She feels strongly that inequity should never be the reason a child does not have the tools they need to be the leaders we'll need in the future!
As Director of Development, Katherine is proud to work with OCC staff to achieve financial goals that allow us to serve all of the children of Ossining - no matter their financial circumstances. Katherine loves being a mom, an aunt, an auntie, and a Girl Scout leader.
