Avi Garelick wears many hats: he runs a Hebrew school associated with the Jewish Theological Seminary in New York city, he is active in Northern Manhattan is Not For Sale, an anti-gentrification group focused on Washington Heights and Inwood, and he’s a member of the Democratic Socialists of America. In this interview, Garelick describes participating in a rent strike when his landlord turned off the heat, how his socialist philosophy informs his role as a manager at his job and how the Jewish concept of redemption guides his social justice activism.
