What truly defines our team at East 57th Street Partners is our unwavering commitment to service. While we bring a wealth of experience and credentials to the table—just like our competitors—we distinguish ourselves through our deeply relational approach. We genuinely value the relationships we build, preferring meaningful connections over mere transactions.

E57 is more than just a business; it’s our calling, our ministry, and our passion. Servant leadership isn’t just a practice for us—it’s who we are. Our team is dedicated to putting you and your needs first, not because it’s a strategy, but because it’s the right thing to do. We believe that the foundation of our success lies in the relationships we nurture. To us, who we are and how we connect with you matters far more than the services we offer.

In Memoriam

Joan Chali

In honor of Joan Chalif…

Joan Chalif was one of our first hires at the start of our firm.  Our company today is modeled after many of the personal touches Joan brought to our culture. Originally hired as a receptionist, Joan went on to run our entire back office, operations and ultimately became the heart and soul of our company. She was our den mother, our guiding light, and the glue that held the company together through all the good times and the occasional bad times. In 1989, she began a long career as a business partner and operations director for Lavinski Allan & Associates. When that business sold, she co-founded Propensity, Ltd. in 2004, where she served as a partner and executive until her death. Joan’s family and many friends will always remember her enthusiasm, encouragement, and positive outlook on life. She was the best friend anyone could ever have.

As a company leader, Joan did far more than put up with us. She drove us all to become more successful, more considerate of others, and just better people. Joan died of cancer on August 4, 2007, at the young age of 61. She was irreplaceable and will never be forgotten. We hope to honor her memory and thumbprint on our culture for all the years and future generations to come at East 57th Street. May her spirit continue to inspire us all!
