From the website:

""The Workmen's Circle / Arbeter Ring is a national organization with members across North America. Created a century ago by Jewish immigrants in New York City, The Workmen's Circle engaged hundreds of thousands of Jews in mutual support and community building, with an inclusive commitment to social justice, and a big tent approach to Jewish culture and heritage. Yesterdays network of lyceums, health clinics, and schools has evolved into todays nationwide calendar of cutting-edge arts programming, our award winning summer camp, our leadership in the Jewish community on social justice issues, and our welcoming national network of multigenerational Jewish communities and educational centers/shules. Today's Workmen's Circle is the organization for everyone who feels at home being Jewish, secular, and progressive.

The Workmen’s Circle plays a central role in the world-wide rejuvenation of Yiddish arts and culture, preserving and celebrating the traditions of Eastern European Jewry while encouraging contemporary creativity. We present exciting music festivals and public concerts, art exhibitions, conferences and workshops, as well as educational opportunities for children and adults in our centers across the continent."

The Workmen's Circle has branches in Boston, Florida, Michigan, New Jersey, New York, Ohio, California and Toronto. It organises the annual Camp Kinderring as well the Circle Lodge Retreat.
