Fall 2019 Interns

Claire Henleben

Claire Henleben is one of two LCA interns this semester. Claire is a 3L at Loyola University of Chicago Law School and holds an undergraduate degree from the University of Missouri in history and political science. Before LCA, Claire was a research assistant for Professor James Gathii at Loyola and interned for the Clerk of the Court in the Dirksen Federal building and in the Chicago Field Office for the Department of Homeland Security. In addition to her assistance with client intake, Claire was especially helpful in helping us prepare for a lecture about legacy in the arts community with the Chicago Women’s Caucus for Art. 


In Memory of Bill Rattner

It is with deep sadness that we share the news of the passing of William E. Rattner on March 16, 2019. Bill came to LCA in 199

9 following a successful 38-year career in commercial litigation, and served as Executive Director from 1999 to 2014. He brought with him his passion for the arts, especially opera, and a drive to make a difference. Bill led the organization through a rough period and rapidly helped the organization regain its standing in the legal and arts communities.


Among Bill’s many accomplishments while at LCA was his Non-profit and Tax Exempt Workshop, which has run for more than 15 years, five times a year. The Workshop became a “must” for managers of many hundreds of start-up organizations, folks with great ideas but often little business experience. Bill helped them navigate the daunting application for non-profit status and provided valuable advice on how to run their businesses efficiently and with integrity.
