Founded in 1911 to serve the children of Immaculate Conception parish (est. in 1853), Immaculate Conception School was originally staffed by the Franciscan Sisters of Hastings. ICS is now fully staffed by dedicated lay personnel, working with the support of the Parish of the Immaculate Conception and Assumption of Our Lady and the Central Westchester Region of the Archdiocese of New York. ICS is guided and led by Principal Michelle LaMassa who has more than 20 years experience in the Catholic Schools of the Archdiocese of New York.
