CSI Staff

Shireen Idroos, Executive Director

A longtime nonprofit manager and development professional, this Los Angeles native is a graduate of Vassar College. Shireen started out at the Muslim Public Affairs Council before working at the Thurgood Marshall College Fund and the Children's Health Fund. Most recently, she spent over five years as the Director of Individual Giving at Her Justice, a New York nonprofit that provides free family, divorce and immigration-law services to women across the five boroughs.

Elizabeth Keane, Director of Business Affairs

Elizabeth is originally from northern New Jersey and attended Suffolk University in Boston for both undergraduate and graduate school, earning a master’s degree in Criminal Justice, but never making it in law enforcement! Her studies, instead, focused on understanding people and society, and how they work and intersect. Her ultimate goal is to use her understanding to help fix the many cracks and imperfections in many of our current systems. On a more personal note, some of her favorite things in life are dogs, a good book, and the perfect cup of tea; ideally these would all come together for a cozy afternoon at her local coffee shop (or CSI lounge area!).

 Theon Freeman, Facilities & Operations Coordinator

Holding community and thoughtful interactions at his core, Theon works to ensure that every person that walks through CSI's doors experiences the magic like he did upon his first visit! As the Facilities & Operations Coordinator he is tasked with facilities upkeep, tending to member requests and inquiries, as well as managing the DECA (Desk Exchange Community Animator) Program. Prior to CSI, he worked in Procurement & Customer Success in both Corporate and Startup environments. As a New York native he feels that CSI is changing the co-working ecosystem, for the better! [Contact Theon]


 Allegra Gilfenbaum, Community Animator

Allegra is a performer, community organizer and Hip Hop enthusiast with years of professional experience at both funded start-ups and non-profit organizations. With an undergraduate degree in Vocal Performance from Bard College, she combined her studies with a focus in Human Rights to leverage music as a lens to explore culture, history and her community. These days, not much has changed as she continues to pursue a career as a vocalist alongside a love for bringing people together to reimagine solutions to some of our most complex societal challenges. Most recently she’s worked with organizations such as NYU’s Social Entrepreneurship Program, The NXT-GEN Fellowship for Moral Leadership and the Hip- Hop Education Center to build community around their initiatives and create operational structure that will help them thrive as they grow. On any given day Allegra can often be found drinking a coffee, watching make-up tutorials, “studying” pop culture and wandering the aisles of dollar stores. [Contact Allegra]

Lexi first witnessed the power of community and social impact at a young age, growing up across the world with parents working in international development. At 18 years old she moved from England to the US, and graduated from Penn State University in International Politics.
