    Cathy Cathy Shields - Events & Volunteer Coordinator
    Cathy's background in medical social work, as well as in bookkeeping, might have made her an obvious choice for her position but, really it was her history of community activism and her love for the values of Park Day School that brought her to this job over 25 years ago.  Before she was on staff at Park Day, she was on the board of her children’s preschools, on the board of Studio One, a political activist and chair of Park Day's major fundraising events. Her three children are all graduates of Park Day School and she says “My children are very different from one another and yet each of them left Park Day confident and capable in life.”
