Executive Assistant

About the Opportunity

This is a rare opportunity for a sharp, self-directed Executive Assistant to support two seasoned Executive Directors at the intersection of the arts and social justice — each leading mission-driven organizations with meaningful real-world impact.

The position is based at 55 Fifth Avenue, New York, NY, the headquarters of Time Equities Inc. (TEI), the real estate company whose founder established all three organizations. This person will be embedded within the TEI environment, working closely with TEI’s accounting department and executive team on a regular basis.

Both Executive Directors are remote, which means this is not a conventional support role. This person is the on-the-ground operational presence — a self-starter who builds relationships across internal teams, manages competing priorities independently, and takes full ownership of projects from start to finish.

Art Omi Pavilions is a pioneering new arts campus situated on a 190-acre hilltop site in Chatham, New York, in the Hudson Valley. The project commissions up to 18 individually designed pavilions — each a collaboration between a distinguished artist or collector and an architect of their choosing — to serve as dedicated, permanent exhibition spaces for their work. Phase One opens to the public in Spring 2027.

Art Omi Pavilions is co-directed by Francis J. Greenburger and Natalie Diaz.

The Greenburger Center for Justice is a criminal justice reform nonprofit that advocates for systemic reforms to the criminal and civil legal systems. The Center works to educate policymakers and the public, advance alternatives to incarceration, and promote a more humane and effective approach to justice — particularly for individuals with serious mental illness.

The Greenburger Center for Social and Criminal Justice (GCSCJ) developed a first of its kind in the national, alternative to incarceration model which provides longer term, trauma-informed residential and clinical services for people living with serious mental illness. The model is being piloted at a facility called Hope House on Crotona Park which is operated by the GCSCJ.

Both Greenburger Centers were founded by Francis J. Greenburger, and together they represent a unified vision for justice reform.

This position provides 50/50 support to two Executive Directors: the Co-Executive Director of Art Omi Pavilions and the Executive Director of the Greenburger Centers. While the day-to-day mix will vary, both roles demand the same qualities — proactive communication, reliable follow-through, and the ability to own projects end-to-end without being managed closely.

The strongest candidate will be someone who thrives on variety, takes initiative without being asked, and genuinely wants to be a key contributor to organizations doing important work. Small teams mean high visibility and real impact.
