ABOUT 11A COLLABORATIVE:
11A Collaborative is inspired by Selda Chender, the grandmother of our founder, Julian Chender. A refugee escaping Mussolini and Hitler, she arrived alone and penniless in New York City in 1941 at the age of 17. Her curiosity, strength, will to survive, and endless pursuit of personal and professional growth embodies our purpose: to build human connection. 

11A was Selda’s apartment number, a place where she artfully hosted gatherings, salons, and family engagements, leaving a rich and lasting legacy. It is this intimate heritage that we bring to our work in purpose and strategy, organization design, change activation, and executive coaching. We facilitate generative conversations that are crafted specifically for the unique needs of our clients. We look holistically at the full system, taking into consideration the needs of the individual and the organization. We use our deep expertise in human behavior to understand the past, define our present, and build for the future. 

As we expand nationally and internationally, we look back at apartment 11A to remember that healthy society is ultimately defined by the quality of our connections, no matter what city.
