When I finished graduate school, I went to volunteer in Israel.  I worked with Inter-Action, a London based organization dedicated to social change through the arts.  They came to Ashkelon for five years and one of the leaders was Liz Leyh, who was a concrete sculptor.  I learned not only how to work with concrete but how to structure art as a community building activity.  The skills I learned in my three years in Ashkelon taught me how to be a successful community artist.
