Barrington Youth & Family Services (BYFS) is a nonprofit organization that has served the Barrington area for 40 years. Our service boundaries coincide with CUSD #220 and we work with families living in Barrington, Cuba, Dundee, and Ela townships located in NW Cook, SW Lake, and NE Kane Counties. This gives us the unique capability to develop or modify programs and services to respond to emerging issues in the Barrington area identified by municipal, school, church, and other community leaders..
