Ms. Chiara was committed to enhancing the lives of individuals with HIV/AIDS, helping to launch New York City’s first counseling program to assist AIDS patients. As a committed member of EXPONENTS’ team, she helped steer the agency through its early growth and development and did not miss a single board meeting. 

It gave Ms. Chiara, great joy to know that through her efforts, many seriously challenged individuals were given an opportunity of a better life and today her legacy of giving continues through the Judith L. Chiara Charitable Fund, Inc.

We are truly grateful for her unyielding support.
