In Memoriam
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!
