In early December 2004, a group of concerned community leaders gathered to address what it saw as a growing problem of homelessness in Northern Westchester County. Reports of homeless men and women suffering through severely cold winters and, in some cases, dying from exposure, mobilized the group to develop a program for a winter night emergency shelter. The core of the shelter concept consisted of interfaith congregations opening their doors to offer a safe place to sleep and a hot meal to those in need of food and shelter.
In 2005, the Emergency Shelter Partnership (ESP) committed to providing emergency shelter during the five coldest months of the year, November through March. In October 2011, ESP became a 501(c)(3) not for profit corporation. In 2018, the Emergency Shelter Partnership joined forces with a similar group in Ossining thereby serving two geographical areas – Mt. Kisco and Ossining. Presently, there are thirty-one congregations that host the shelter; working side by side with other community groups and individuals who provide meals and financial support.
